Fuel pump recommendations.

I am replacing the fuel pump on my '69 F100 (I hate the canister filter). I need opinions on this fuel pump. From what I have researched Holly is a pretty good brand and this seems like a good match to my 302, which is 100% stock. I want to keep it mechanical, and from what I have read this is about the right gph for the stock 302.

Also, can someone explain to me which gasket is better, silicone or rubber with steel core? I am replacing my oil pan gasket and am leaning towards Fel-Pro (past experience has been good with them), but I am open to suggestions.


Many thanks.

I wouldn't buy that pump. Stock 302 won't need 8 PSI. Closer to 6. And $125.00? OUCH. It would Look Cool though. Eye candy. On the gaskets , if you're using a stock steel pan, between those two choices I'd do the rubber with steel. The silicone gaskets are usually meant for an aluminum pan with flat rails that's meant for a silicne gasket.

That is very good, much appreciated info.

Now I have a secondary question: what GPH would be good for a stock 302? I see everything from 80 GPH to 170 GPH. I know that you can calculate it based off of horse power, but I don't have a clue what a 45 year old 302 puts out... What is commonly run on these engines?

Many, many thanks.

A stone stock 302 of this vintage puts out about 200 hp.

"What Size Fuel Pump Do I Need?" Your Top Tech Questions Answered! - OnAllCylinders

So according to Summit Racing, to figure what you GPH you need to use this formula (I am sure you guys know this, I am just fact checking):

Optimal GPH = (Max. HP x BSFC) / 6

So 200 HPx.50 pounds of fuel per horse power equals 100 pounds of fuel per hour divided by 6= 17 GPH (16.6, but I am just going to round up to 17).

So if I need 16.6, and pretty much all pumps I have found are 80 GPH at the low end with 170 being on the high side, am I going to constantly flood my engine out?

That's where a bypass regulator and return line come into play.

Bear with me here, I am learning all this 100% on the fly.

The primary purpose of a return line is to prevent vapor lock/ return fuel from the pressure regulator if one is installed.

A bypass regulator keeps the PSI to a set point when paired with a higher powered fuel pump.

However if I use a fuel pump with a preset PSI (around 6 PSI as suggested here), then a bypass regulator becomes a moot point. Like this pump bellow: it has 110 GPH but only 6 max PSI, which should keep the engine from flooding
without a regulator.

http://www.summitracing.com/parts/ed...l/f-100-pickup


Now, this engine won't be stock for ever because I plan on building it to around 300-350 horsepower; I am just building the fund pile before I go crazy.

Now this fuel pump is 110GPH too, with preset 6.5-8 PSI. I think this MAY be better if it won't cause flooding with the currently stock engine, it has a slightly higher PSI which would work better with a modded engine. It also says that for this pump that a regulator is not required; I assume the same is true with the other pump listed above because I don't see a difference in the build.

Actually, IIRC, my 72 F-100 302's doortag said 133 hp at 4800 rpm.

As of right now,bone stock, I'd go plain ol' stock replacement pump. Your 302 isn't going to be buzzing the high RPM that much fuel pump is for. I am assuming anyways. If you are keeping it carb'ed, good luck keeping needle and seats in it with the amount of pump you want to use. Nothing personal, I think you are commiting Overkill. To the Max.

Agreed. I've got a mild 351 with an edelbrock package. I'm running a stock pump. No problems.

orich is gaining momentum as a positive member of FTE.orich is gaining momentum as a positive member of FTE.
I'd say it should be find with a 750 Holley double pumper at the drag strip.
If not racing it then better have a regulator on it to tone it down the psi a bit.

Well, it is only going to be stock for about six months until I pull it and rebuild it from the ground up. New crankshaft, manifold, four barrel carb, headers, seals, ect. This is to keep it rolling down the road.

At only six psi I THINK it will be fine.

It has a stock 3 speed tranny, so it is actually running fairly high RPM's (2,500 range).

What PSI does it need? That pump is preset to a max of 6.
