Mystery Fuel Pump - Help Needed!

LurkinLimey · Jun 30, 2020

Hi Everybody,
Need some help - The electric fuel pump that came fitted to my Big Block has failed (cooked by the headers I'm guessing) and I need to replace it.
Problem is I can't identify what it is - only identifying mark is 1001 stamped into the ally housing.
Anybody out there have any ideea what it is?
Also, it's the only fuel pump on the car - should I have a pusher pump down near the tank too?
Any help appreciated - hate being off the road!
Cheers,

Can't help w brand etc, but no matter the electric fuel pump, they should always be mounted w/in 2-3 feet of fuel tank and below the level of the tank if possible. Does it feed a carburetor or fuel injection. If a carb, there are some good quality low pressure inline fuel pumps out there. No need to purchase a super expensive hi pressure one.

I just looked at the gauge, it has very low psi numbers so I'll assume it's carbureted. I run a Walbro on my turbo, blowthrough carburetor jet boat. The pressure regulator keeps my pressure good and it flows enough volume for 600+ hp. A return line from regulator will increase the pumps life as it won't heat up as much. Mine has lasted 5 yrs in 120+ degree ambient heat with extreme vibration.

Thanks man - Appreciated. Should have said. It's feeding a single Holley 750 on an Edelbrock intake on a 383 stroker.

If it's possible, I'd go back to a mechanical fuel pump. I run electric on my boat because the engine has no provision for mechanical and it's turbo so it needs at least 21 psi. So many guys running big blocks w blowers using mechanical pumps on jet boats w no starvation issues. They pull tons of fuel, more than any street driven or 1/4 mile street driver will ever use.

Agreed. The extra pressure drop from the long inlet run was as hard on it as the heat, maybe more so. I would either get a nice factory Carter mechanical or a new high quality low pressure electric back by the tank, mounted low as it should be. Inlet restrictions or long runs for electric are way worse than an outlet restriction.

Thanks for the advice guys - Will give it some thought.
Still like to know what the hell the pump that came in the car is though....

I would also suggest trying to replace the rubber line with metal or braided hose.
Particularly with an electric pump.
