?? what externally mounted electric fuel pumps have you gentlemen found work well & are durable

[Grumpy]

obviously there's hundreds of options , vendors and brands read carefully,
and Ideally try to find a fuel pump that had both the correct port size for the fuel lines and flow capacity.
at the ideal pressure range you need and ideally at a reasonable price and from a trusted vendor.
first determine the type of fuel pump you need(internal in the fuel tank like the C4 corvette )
or a manual engine mounted fuel pump
, (or an external electric fuel pump)
many BUT NOT ALL<muscle cars benefit from swapping from the factory manual fuel pump to the frame mounted electrical fuel pumps


here's a few options please add what you've found and used along with the rated flow capacity and price.
personally I think most people fail to read or just don't understand what the pump pressure and flow capacity ratings mean, keep in mind most pumps for carburetor use require a fuel pressure regulator and most pumps for EFI use are mounted inside fuel tanks on systems designed to use a FUEL PRESSURE REGULATOR AND RETURN LINE

Return Line in fuel system?

Is it possible to plumb the return line of the fuel system to the fuel filter near the gas tank or in the feeding fuel line via Y fuel block? I thought about the Y block to not interrupt the fuel flow like when using a T block. I ask that because my original gas tank (1955 Chevrolet) has no plug...

too much or too little fuel pressure?

Need advice. I have a 1956 Chevy truck. The problem I'm having is every time I put the gas pedal to the floor the truck gets up and takes off. After I let off the gas the truck sputters and dies. I open the hood and look at the fuel pressure regulator it reads zero and won't pressure up. I have...

Input on electric fuel pump selection

Not sure what that will do for electric pumps having to pull the fuel from the mat, Does seem to be a viable option vs the sump, a bulkhead fitting and some hose would do the trick, as everything car related cost will be the primary driver as to how much of the market it will corner. Neal

Can a mechanical fuel pump be too big?

What I mean is, can it be moving too much fuel? I know the formula for figuring out minimum fuel pump size, I know how to account for restrictions of fuel lines, fittings, etc. But say you're running a 150gph pump, when your engine only requires maybe a 80-110gph pump (again, correcting for...

Here’s a couple of electric fuel pumps I’ve used that have worked well for me.

1) Holley HP-150; PN 12-150; 140 GPH @ 7 psi, internally regulated at 16 psi
$385.95 at Summit Racing Equip. (includes a PN 12-803 pressure regulator)

This pump was installed a 71 Chevy Nova I bought back in 2006. It had a 350 Small Block Chevy with a 200HP N2O Express Hitman N2O plate system on it. The pump supported both the engine (about 400 HP) and a 200HP shot of nitrous with no problem. Here are some pictures of the installation:







I was running 13.44 @ 101.6 MPH NA and a best of 11:41 at 118.5 MPH with 150HP N2O shot at the time.

Since per NHRA rules I should have had at least a roll bar at 11:50, a friend and I installed a 14 pt. roll cage in the car. During the timeframe of the cage installation I bought a 650HP 408 ci SBC crate motor (detailed here) and installed it in the Nova when the cage was completed. It ran a best of 11:21 at 121.29 MPH NA. The fuel pump again worked flawlessly. Here are some pictures of that installation:






I sold the car to my son who got sideways in it at 80 MPH at the drag strip and kissed the guardrail which tweaked the frame so we retired it. I took the pump out of the car and I am now installing it in my 71 Nova. I will detail its latest installation in an upcoming post.

The fuel pump worked great in the installations detailed above and will next be put to use in my Nova. I would definitely recommend it for performance and reliability.

2) Mallory Comp Pump Series 250; PN 5250 (discontinued; new PN 29269) 250 GPH @ 18 psi bypass pump approx. $650; I found one at Jegs: Mallory Fuel Pump & Relay Kit - Gasoline .

I used this pump in my 69 Nova race car, but it appears that the PN 5250 was superseded by the PN 29629. It was another good reliable pump I had experience with. Sadly, I think it was discontinued after Holley bought MSD/Mallory. Here are a couple of pictures of its installation for information.

Looks like a quality installation on both cars !
