I understand that FE fuel pumps are compatible with our Ford Y Blocks. My engine seems to be starving with the stock fuel pump. It actually starved and stalled once at Columbus on one run and my RPM's are limited. Are there different versions of FE fuel pumps? I would think that 406/427 and other high performance pumps might be different. Does anyone have any suggestions?, part numbers? I know I should be running an electric fuel pump too. What's a good electric pump to use?

Go to summit racing, and you can search for them by engine application and flow and pressure. That will be the best way to find one that is sufficient.
I wouldn't expect you to need electric but... So far I've only used Holley and Carter electric pumps. The Holleys are junk. The carter has lasted almost 3 times as many miles as 2 Holleys combined and it is still going. I think I got about an average of 800 miles out of each Holley - not good at all for a daily driver. You also have more latitude for mounting the Carter. It's design is such that it can be something like 18" higher than the top of the tank and still work. I'm not sure if that is the correct figure but it will say in the instructions. The Holley has to be below the tank. The Carter is also made in the USA, if you care about that, or at least it was several years ago when I got it. Hopefully they still are.

This chart is for one of the Holley 80 GPH mechanical pumps..... the FE pump for a 428 ought to be good enough like the Airtex 362. Note that the free flow in GPH is not anything like the real flow with back pressure. A 300 HP engine wants the GPH to stay over 30 when the engine is flat out. At a useful mixture, engines like to have about 1/2 pound of fuel per horsepower per hour.
The mechanical pumps have to have a big enough line to keep the required suction/vacuum down to a minimum. It is easier to handicap a fuel system on the suction side of the pump than on the pressure side.

I'd agree with Charlie on the Electric pumps. Skip the Holley. Summit Racing carries a pump under their own brand name that does work (and last) pretty well. But a CJ mechanical pump should be all you need.

Paul J : Ofcourse you understand that F.E. pumps don't have the wiper vacuum feature? And for what it's worth, in the group of old car guys I have coffee with, I haven't heard anything that convinces me that electric pumps are any more reliable than original equipment pumps..

Your standard pump should not be leaving you short, is your motor heavily modified?
You guys running a return line for the electric pumps, the Holley mainly wont last if you don't.

I have a pump on my 292 from a 390. It's been working well for about 5 years now.

On my supercharged motor I'm using an Edlebrock Performer #1724 fuel pump (Ford Big Block FE) rated at 110 GPH. It uses 3/8" inlet and outlet. On my 56 Customline I have been running a Holley "Red Top" electric fuel pump for 5 years without any problem (so far)...guess I've ben lucky!!

Your setup may be experiencing vapor lock. Or just inadequate fuel. Like Paul suggests if you ditch the pump entirely, No wipers.
I would suggest running an electric Carter style pump inline if you want to remain somewhat stock looking. Then you get to keep the original style. That's more or less what I've been doing for years. The carter is on a manual switch. It is also used prior to starting my car. I let it pressurize before I touch the key or throttle. Works well and again it's how stock or original you care to look..

Thanks for all the input and suggestions. My engine is a 312 E Code with rebuilt Holley 4000 quads, .060 over with Probe forged domed pistons, half of domes milled off to reduce compression so I can run pump gas, and Probe forged rods, balanced, decked block, Isky RPM300 cam and kit, new SS stock replacement valves, roller timing chain and Melling oil pump, and new improved oiling rocker arm shafts. I am running stock exhaust manifolds with glass packs. My engine doesn't want to rev past 5,000 RPM. I have a new 4.10 gearing with limited slip differential. This year at Columbus it ran a best of 16.29, on a 16.30 dial in My plan is to convert the car to a T85 OD. Since the car is a numbers matching E Code, I want to keep it stock appearing. I am converting the wipers to electric so I don't need the vacuum port. Summit has mechanical pumps by Carter, Edelbrock and Holley, all around $100.00 + -. An electric pump would be nice too, when my car has been sitting for a while, it takes a fair amount of turning over and pumping to start.

I'm with Frank - a 428 police interceptor or CJ pump will do the trick no problem.
Bird55 has a really good point though - many of these outfits just can't get enough fuel pulled from the tank through a 5/16 line and tank strainer. The 3/8 suction line is a really good approach to this - doesn't need the electric pump.

Green is right-on...you need a bigger fuel line with no 90o turns..sweeps are OK. I would go with 3/8" ID.... If you like AN stuff thats a -8......JD

"-8" refers to 8 sixteenths. That used to be 1/2 inch where I live.

I think I will try the Edelbrock Performer 1724. If possible, I would like to keep my trash can fuel filter that is a part of the E Code package. The fuel pump I have on the car is a rebuilt that I got with a very large collection of parts I bought a few years ago. I think the fuel sediment bowl fits under the Edelbrock pump like the stock pump, is that right?

I have the holleys mechanicals on my 390s have had no troubles with them. Summit actually has one with their brand on it its cheaper than the others and when you open it you can see the glue where they peeled the holley sticker off of it. I dont believe that you can run a sediment bowl under any of that style pump

Sometimes I point out the obvious. In this case, it is that these fuel systems were designed to utilize vented tanks. The venting was done via the fill neck cap.

I hate to say it but one thing that the Garage mans Companion's had over the FORD products of the day was using a 3/8" fuel line over the FORDs 5/16" and the best way to increase fuel flow is to increase the line. On Our stock Cars in the early days before Safety Regulations made us go to steel line we used rubber fuel hose as it was easy to run thru the frame. man what a difference. The A/C mechanical pump performed for several years and was still on the car when I sold it years later.

Paul:
Keep in mind that the teapots don't like fuel pressure above 6 psi, it causes the needle valves to unseat and flood the engine. If you get another pump with higher pressure than that, you may have to add a regulator.

Hoosier,
If I'm running a FE HP fuel pump and a inline pusher electric in the back do I not need to consider a larger fuel line? I do have a pressure regulator between the mechanical pump and the carb.
Once I get the 4-71 supercharger up and running will that change things? I understand it a matter of volume and/or pressure. Chuck

Chuck:
A larger fuel line is not a bad idea, you don't want to lean out on top end. I fought lean out for years on my car. The 471 will be an easier setup to supply fuel to, because the carb will not be a blow through like the Paxton setup, the carb will be a draw through and think it is normally aspirated. I assume you will use a later Holley or Edelbrock on top of your 471,so it will have two needle and seats. The single needle and seat of the teapot restricts the amount of fuel it can pass, so it chokes the horsepower. I think I remember Gordon Payne telling me the single needle and seat will allow enough flow for about 350 HP.

Paul;
It wasn't clear to me from your initial post if your new fuel pump is for a Paxton/McCulloch set-up. If it is, you will also need to boost reference the fuel pump to the carb bonnet. I used a barbed hose fitting threaded into the top of my Edlebrock fuel pump.

Chuck, Go with at least the 3/8's line. If you have to run a return line, 5/16 would work, but 3/8's costs the same so why not?

Rono:
In a later post, Paul said his car is an E code with dual teapots. No blower, no boost, no need for boost reference.

After reading this, I think I'll go with 3/8". I have to make a new line anyway. The only mod my engine is seeing is a 265 cam ground by the rebuilder and ram horn exh with an h pipe and a pair of generic mufflers. I am a cheap b@$t@*d but if it's the same cost.................
