I was looking for a Hi Output fuel pump for my 1973 Cleveland 2V, now with 4 barrel intake and 750 carb. With the "509" lift cam, and a higher stall torque convertor, I am planning on running some more RPM, and wondered if I might want more fuel pump output.

Then I saw one on E-bay, hi-output, rebuildable, and only $35.00.

So I ordered one up. It took 2 weeks to get here ( to Canada), unusually long, and when I contacted the seller they said it was delivered already?
When I did get it, I did the usual thing, grabbed the lever and give it a pull. Nothing! Like it was stuck. I removed the plastic plugs in the fittings, still nothing.

Good thing they are rebuildable, so apart it came. Remove the screws and the pump comes apart. Drift out the pin, and the lever arm comes out. That is where the problem was. The lever was jammed in on top of the spring and mounting cup, when it should fit under the cup and on top of the spring. Those people in China are in a hurry! Correctly assembling it , the pump now has a good stroke, and makes "pump" noises.

I think it will work. Has anyone else used a fuel pump from Speedmaster on E-bay? My stock pump still works, looks like it is original to the car, so must be reliable. I might just hold off installing the speedmaster pump for a while.
The speedmaster unit is pretty, chromed up, and here is a pic.

For mechanical fuel pumps, there are a lot of cheap ones out there. Stay with Carter. I've also had good luck with Edelbrock's fuel pumps. I'll dig through my Ford Racing catalog. It has information on how to calculate fuel requirments based on horsepower.

Just another example of Chinese craftsmanship. No I've never used one of these my stock one does the job but I'm running stock cam and running gear and have no need. It's a good thing you checked it instead of just trusting it to be assembled correctly and bolted it on.

Your stock pump should supply plenty of fuel, even with 4BBL, cam, etc. Your fuel line to the carb. should be 3/8". I have several mods on my 4V Cleveland - stock pump, no fuel starvation issues.

I installed a new line from the tank to the fuel pump, so I might as well put in the 3/8 line to the carb. The Chinese pump will likely work, now that I "rebuilt" it.
Where can you buy a higher output fuel pump by carter, for a Cleveland?
I know there are lots available for Windsor motors.

Sorry, I never thought fuel pump availability would be an issue. I run a 351W. You can switch over to a 351W based motor. They make more power than most people are aware of.

The only Carter brand Cleveland pump I saw was their Muscle car series at Summit Racing, which is basically a stock replacement pump.

I'll post that fuel requirement info from Ford Racing in a while.

I agree with GXR The stock pump is more then capable of providing the fuel. I would as others have said and stick with a Carter fuel pump. Just my thoughts, JTS 71 Mach1

I would agree, most of the time a stock fuel pump is fine for street applications. In that case, the Carter Muscle Car Series is my first choice.

Just for reference Ford Racing and Edelbrock discuss the gasoline requirements based on crankshaft HP and engine efficiency. They discuss it relating to sizing fuel injectors. In my opinion, from an engineering standpoint, since it is based solely on HP, and engine efficiency, I would think it can be a general guideline for the fuel requirements on a carbureted engine as well. Both Ford Racing and Edelbrock have the general gasoline requirement of 0.5 lb./hr. per horsepower measured at the flywheel. The specific weight of gasoline is 6 lb./gal.

For example:
1) 400 hp at the flywheel x 0.5 lb./hr per hp = 200 lb./hr. of gasoline required.

2) 200 lb./hr. x 1 gal/6 lb. of gasoline = 33.33 gal./hr of gasoline required for 400 hp at the flywheel.

I'm sure you'd want a little more for a safety margin. Plus, I would guess a carbureted engine is less efficient. But it seems reasonable since most V8 stock fuel pumps have flow rates in the range of high 20's(gal./hr.) to low low 30's(gal./hr.)

Here is a link to Edelbrock's discussion. It has a little more information.

That fuel requirement is at WOT max power? My 8.2ltr Caddi Eldorado had a stock pump with 3/8" feed and 1/4" return. Never ran lean.
