You need a 5 pole relay.the poles are numbered 84 - 85- 86 - 87- 87A. Need a diagram? GO online.me typing the whole procedure here will get exhausting. You can go to ANY junkyard and find these relays.SUPER DUPER COMMON.
Saabs have a bunch of them.BMW's many cars. Basically you run power and ground to the relays solenoid (or rather you starve the solenoid of one of the connections.I like to switch using ground).then you pipe in whatever type of connections you need to make and break to the other side of the solenoid.at rest the solenoid connects 86 and 87a I believe.when energized it will connect poles 86 to 87. I will grab one of mine and look on the side of it.theres a handy dandy breakdown of the poles and the solenoid on the side of most relays.

Let me know if you need more help and I will draw you a diagram in Paint and post it. SCREW IT.heres what you need to read. I've become a bit of a whiz with relays ever since I learned how to do custom stereos alarms remote starts.Did that for a living too at one point jeez almost 18 years ago now.lol Your setup will only need 4 poles.you will be energizing and de-energizing the solenoid and that solenoid will make and break the electrical connection for you without putting a ton of load on a little switch.that is their primary function.they work like a charm and are very reliable.let me know if you need more help.
I stole the name from my motorcycle The MIGHTY CBR1100XX. Are you saying that you cannot locate a new mechanical Fuel Pump?
You gotta be kidding.They are available I PROMISE you. I will send you links. I am certain you will be able to buy a new one that will last you many many years.
Is that what you are saying? Is this a Slant 6 or the 340? I can find both.I have access to one of the largest part warehouses in the area.they will have it or can get it in one day for sure. I will let you know. Others on here will find them too and may beat me to it.Im running out the door at the moment. BUT.HEY GUYS.SHOW HER A NEW MECH FUEL PUMP EH?
Watch me be wrong and for some reason this part is no longer available.I cant see that happnin tho. Heres one on ebay. EZ Peasy Japanesey.might be made in USA tho.but you get the idea. Wiring up a relay is easy on an application like this but there is one thing you should keep in mind. Vehicles with electric fuel pumps are required by Federal law to be set up so the fuel pump will not continue to run after the engine stops due to an accident.
On a deal like this the law would not apply to you but it is a safety issue. The reason for the law is to prevent a pump from continuing to dump gasoline from a ruptured fuel line onto an engine fire. The relay can be set up to operate whenever the key is in the RUN position or with a little ingenuity it can also be made to operate only when the engine is running. This may involve triggering the relay off of the starter solenoid circuit, tie it in with the voltage regulator, etc.
Another option might be to pirate an inertia switch from a Ford and wire that in. It all depends on the route you choose to go. Just something to be aware of anyway.
Awesome- i should be either hondascrambler, or hondaascot. Working my way to an 1100! It's the slant 6, 225ci, which becomes a 3.7 liter. It's not that i couldn't find one, it was more the time frame i wanted/needed one. Again, really, more personal reasons.
I will GLADLY accept links. I went through several sites, and they said what turned out to be far longer.

And the ebay link(thank you) is for a different style, the one in the dart currently has a carter pump. If i do the mech i'd like the same one.
When i'd called a few days ago, the fellow said it wasn't in stock there, called a few other places, same deal, no matter what the site had posted. What i couldn't locate in town was a working fuel pump from a junkyard- crazy, yes. Louisville doesn't have that many that aren't picked over regularly- just bad timing, i think.
I'll check the link that have been posted, with big-time gratitute! I REALLY wish you wouldnt go with the electric pump. Is there a major reason for not being able to wait a day or 2? I dont want the electric pump on there.
Please go Mechanical. Where are you located.I can find you the part via my warehouse.because they are strategically placed all over the country.I will be able to get you one thru them on my account and all you need to do is use your card or cash to pay for it. AND it will be cheaper than anywhere because it will be under my mechanic shop account.saving 25% or more in every case.Where u? The Federal law on electric fuel pump operation has been around for many decades as far as I know. It was first mentioned to me at some VW and Subaru service schools way back when.
1980 give and take?) The elec. Fuel pumps on carbed Subarus were controlled by the voltage regulator. The theory was that when the engine stopped the alt.
Would quit charging. This would interrupt the circuit for the fuel pump. The downside was that an alt. Or regulator failure, broken alt. Belt, or even a very loose belt could cause the fuel pump to become inoperative. If the Dart were mine I'd just put a mechanical pump on it and be done with it. The only reason I can think of for switching to an electric fuel pump on your Dart is that you have a worn lobe on the camshaft and a mechanical pump won't work.
This used to be the reason in early time periods for going with an electric fuel pump on carbureted engines. If this isn't the case, I think ou would be better off to stick with a mechanical pump. One rason that mechanical fuel pumps sometimes caused the lobe on the camshaft to wear was that some fuel pumps had a vacuum booster side to operate the vacuum wipers. This exerted more pressure on the camshaft to operate the pump. I'm quite certain that your Dart has electric wipers, and I would guess that the cam lobe is just fine.
Electric Fuel Pump: How to Do It Right Want an electric fuel pump to last forever and work right? We're going to show you how to install it and wire it up the correct way! Ok, let's talk about electric fuel pumps. There is a lot of confusion and misunderstandings about them. There is also alot of potential danger when people don't do it right because they don't know the right way to plumb them in or wire them. So, let's break it down: When do you need an electric fuel pump? Is an electric fuel pump reliable?
How do you keep an electric fuel pump safe? How should you wire an electric fuel pump?

-When do you need an electric fuel pump? Usually, a mechanical pump is preferred over an 'aftermarket' electric pump. They tend to be more reliable. However, sometimes that won't work. In my old '47 Chevy, the engine I had swapped in had an issue. The crossmember was in the way of the mechanical pump. So, I ran an electrical pump and had many trouble free miles.
Sometimes, people will plumb them inline with a mechanical pump to add more volume and pressure. This is more for a full on drag car though.Is an electric fuel pump reliable? Yes they are.
Hey, there's about a billion cars running around right now with them. All new cars have them. With aftermarket pumps though, YOU have to install them. That's where some problems can start.
We're here to show you the right way to do it! So, what do I use? For a stock or performance street car, I like these Facet/Purolator pumps from Napa. They are quiet, and work well. Alot of people complain about some aftermarket pumps being junk, but usually there is a reason they go out. It's often the way the person installed it. There are a few things that kill them.Do not run them dry.Always run a filter before the pump.Keep them as close to the tank as you can.
Electric pumps push fuel much better than they can pull it.Mount them away from heat sources such as exhaust.Electrical power to them is everything. You must have the correct wire size to it. A relay is preferred. You may be getting the proper voltage to it, but not enough amps. Remember, the longer the run the more the power will drop.Also, the grounding of it is critical.
Many people will scrape the area where they mount it, or even add a ground wire. However, they forget that they don't have a good ground from the body to the frame or to the engine. This will kill pumps real quick. Tip: Screw into metal to ground, not through it. 'Star' washers are your friends.
Preferably, run a ground wire to the front. Many professional auto electricians will run ground wires from a unit to a common grounding point in an older car, just like in a fiberglass car. That way, there is no question if your ground is good, and it's just 1 extra wire. Once, a buddy and me were going to a show in his '26 Buick roadster. It was built much like a T-bucket and it had an electric fuel pump. It was wired in correctly, and grounded by screwing into the frame by the pump.
We were about 50 miles out, and the pump quit. What happened was the older metal of the frame simply wasn't carrying the current well enough. The pump overheated and shut down. Fortunately, he had some extra wire and we screwed one end to the ground wire at the back and ran it to the front where we attached it to the negative side of the battery. The pump started back up after it cooled down and we were trouble-free all the way there and back. When we got home he wired it in neatly and never had a problem after that.How do you keep an electric fuel pump safe? Electric fuel pumps can be dangerous?
Yep, without some way to automatically shut them off, they can be VERY dangerous. But they don't have to be. If something lets go in your engine bay like a fuel line, the engine will eventually quit. However, if you don't have a way to automatically shut off your electric fuel pump you will keep spraying raw fuel all over your hot engine and wiring. Also, in a crash, your pump can continue to run feeding a fire if you don't have a way to stop it.
Note: Never mount an electric fuel pump in an enclosed area such as the trunk or interior space. Ok, so how do I do it right? The easiest way is to use an oil pressure switch. The switch will stop the pump whenever the oil pressure in the engine goes away. So, whenever the engine is off, the pump will turn off automatically. Some switches just do that. But how do I get the pump to run when I'm trying to start the motor and the oil pressure's not up yet?
You use a three prong switch like this Standard Ignition PS-64: The switch will also let the pump run when you hit the starter because the engine doesn't have oil pressure yet. One wire goes to the pump, one to the start circuit, and the other to the ignition circuit.
So, when there is no oil pressure, the switch connects START to PUMP, and as soon as you start cranking it runs the pump. When the oil pressure comes up, the switch connects IGN to PUMP, for normal running. When oil pressure goes away (because you just hit that rock and tore the pan off the engine, for example) it again connects START to PUMP, and disconnects IGN from PUMP, so the pump shuts off. Don't worry, it's easy to wire.How should you wire an electric fuel pump? Since you need the fuel pump back by the tank and at the same level as the fuel or lower, that usually means you're going to have a long run of wire. So, you need to have really good wiring going back to it.
Wiring that will carry enough current. Running the current through your ignition switch isn't a good idea since it's probably already overloaded, and will kill the voltage. That will kill the pump. However, it's nice for convenience. That's why a relay is really good to use.
It lets the ignition switch activate the pump, while keeping the power from having to run through it. It will keep your pump alive and happy because it is getting full voltage. A good way is to mount a relay beside a power distribution block on the firewall (see Improved Power Circuit) and get the power from there. Here is a diagram on how to wire and plumb your pump.
