Electric Fuel Pump Recommendation

[Vin Man]

As part of my engine upgrade, I would like to replace the stock fuel pump with an electric fuel pump.

The engine is a 200 ci inline 6 with an OZ head. I'll be running the HW5200 2bbl carb.

I'm putting in the 264/264 112 cam from Classic Inlines.

What fuel pump would you recommend and where would I acquire it from? If I'm getting it from Checker or Autozone, what do I tell them I need it for (they need year, make model, etc.).

All of this is going into my 67 Mustang. Thanks.

Is there a spec on what the carb needs???

On my 74 bronco with a stroked 302 and holley truck avenger 670 cfm I'm running a electric pump rate for 5-7 pounds. Got that one from auto zone

On my 66 with a stock 170 and autolite 1100 the electric pump is rated for 3.5 to 5 pounds. Got this one from napa

Check out this site and info for electric fuel pumps. http://www.racetep.com/webfuelspark.html#webfuel
You can get the Carter pump cheaper from other places, (PAW, Summit, etc)

Everything I have read and experienced indicates for the best results you should get one that uses a return style regulator. Longer and quieter pump life. Greatly reduced chance of vapor lock. Dont forget to rig up some sort of safety switch. Most common is through an oil pressure switch. You can build them yourself or I think buy them from places like jegs and summit. Basically if there is oil pressure pump runs, no pressure (like a stall) pump quits. Most of the time there is enough fuel in the bowl so you dont have to worry about starting. Some people set up so that it also runs durning cranking.

You want some kind of safety switch. Some people have hook up "motion switch" that shut off during an accident. Most use a oil pressure swich. Both have their pro's and cons. ( accident w/ motor still running vs stalled motor).
Either way you want to run it from a relay.

The 'motion switch' is usually called inertial. This was/is common in Fords.

Thanks, I was drawing a blank on that name.
Here's a link to a inertia switch explanation http://www.therangerstation.com/tech_library/InertiaSwitch.html
I think both the inertia switch and oil pressure switch has their pro's and cons. With the oil switch, if the motor stalls fuel pump is off and also no fuel pump if ignition switch is left "ON" for working on the car. But no protection from an accident. The inertia switch has protection from an accident, but if your motor stalls pump keeps running. I guess the ultimate protection would be both. I little extra wiring but not too hard to wire both in series.

Lastly, you want to install a fuel filter BEFORE the fuel pump. Dirt and debris will kill a pump quickly.

Ohhh - I hadn't thought of that. Great suggestion!!! Thanks.

Be sure to select the proper pre pump filter. Electric pumps dont suck worth a darn so you dont want to do anything to slow them down. If you look at fuel filters in jegs summit type of places you will see various types listed. Often the pump has a recommended type or model.


I think Gm's theory with the oil pressure was they just wanted to be sure the pump would shut off if the line was ruptured. Line rupture on EFI car means engine quits, oil pressure drops, pump shuts off. With a carb it may not work as slick but at least in the case of something like a stall its not going to quit pumping. A guy down the street from me burnt his house down because of a stall. It was a 40's Lincoln, he just came back home for something quick and was partially in the attached garage. He must have got a phone call or something and got distracted. Engine stalled for some reason but electric pump kept running and overwhelmed needle and kept pumping. THought is hot puddle of fuel evaporated and caught a spark somewhere. Ended up tearing down the whole house. I guess fuel ran down a crack in foundation and caught basement on fire.

Mount it as close to the fuel tank as possible because they do push the fuel better than they pull it, and the heat from the engine bay can be hard on then and cause other problems.

I just installed a carter fuel pump. I mounted it along the frame rail right where the fuel line has a clip bolted into the frame. I actually used the bolt for the clip to mount the pump. I do need to follow up and add another bolt or two to the set up.

I have noticed much better acceleration and a lack of hesitation on corners with the pump. I got the idea for the kit from http://www.racetep.com/webfuelspark.html, but I purchased through Summit as I needed some other stuff.

I can say that it needs a kit to make it a bit quieter. The pump is noticeable at low speeds. I have not noticed any problems by having the pump located where it is. It is below the tank so it has no problem with "sucking".

I'll try and get some photos soon.

In most (if not all) cases the instructions tell you to mount it as low as possible relative to the bottom of the tank. I think the idea is the natural siphon action will help it to stay primed.

I always hear people complaining about the noise. Mostly seems to be an issue with the return regulator less designs. I used a Holley pump, I think the 927. I can only hear it if I listen close when the engine is not running.

Here was my mounting solution, only works if there is a flange on the tank. Some sort of shield is on the to do list but has not happened yet. The clamps are 'beam clamps' from a hardware store, the rest came with the kit.
