Hi folks.
I'm running a 454 with a electric fuel pump in a 57 belair.
My question is the pump placement. From what I have read it is best closer to the fuel tank instead of in the engine compartment.
I have always got great info here and was wondering what the good members here thought about this,and would welcome any thoughts.
Thanx for looking..."T"...
P.S. carbureted with 2X650 cfm

You read it right .Try to keep it away from exhust pipes too.

Ideally an electric fuel pump should be gravity feed. You can't do this with the OEM style fuel pickup.

Electric pumps are really bad at making suction, while mechanical pumps are very good at it.

The problem with gravity feeding an external pump is that is you must weld a fitting on the bottom of the tank, and usually that's a hazard to getting damaged.

It's best to use a mechanical pump. Holley and Edelbrock make BBC mechanical pumps that fit most BBC swaps.

Another way to do it is to use an in-tank pump, like is typical for fuel injection.

One more thought to add to Rick L's:

If you mount an exterior electric fuel pump, make sure it's accessible for easy replacement....because they tend to burn out from the heat they generate when running all the time.

That's why its best to go to an in tank pump setup...so its submerged in the fuel thereby keeping it cooler when it's working.

And for sure, if you stick with the exterior pump plan, keep it as far away from the exhaust pipes as possible, because those just add to the heat woes which decreases the longevity of the pump.

I ran a electric pump right off the connection for the fuel tank for years.
Yes electric pumps aren't great at sucking BUT they won't have a problem sucking 8 inches worth of line. It when you mount them further away when you run into problems.

Another thing, you don't need a crazy big Holley fuel pump flowing like 97 gallons a hour unless you are running a crazy souped up engine.

Basic carbed engine, maybe a bit more, this would probably work for you.

Remember what I said not needing a crazy high GPM flowing pump... Well what happens when a pump WANTS to pump fluid through it but can't (or should I say restricted) it strains itself, over heating or burns itself out..

Unfortunately, my block isn't set up for a mechanical pump. (marine block).
I have a good holley pump that should be enough for the 2 650 cfm carbs. It has worked set up on the side giving me the 7-9 lbs. I need.
Gonna go with this first, and then to the in-tank style if the holley dosen't cut it.

Okay, I've decided that I need a new tank so, why not get one that accepts an in tank pump?
My question is this...The in tank pumps I see are for EFI and have high pressure. Is there a pump that would work with my 2x650 cfm carbs (6-12 PSI) that would match the in tank mounting of the EFI pump?
As always...Thanx for looking.

The TBI setups for 88-95 Chevy pickups were only 12-13 psi. They had in tank pumps that look very similar to the higher pressure Chevy EFI pumps.

Thing is, the pump doesn't determine the pressure, the pressure regulator does. So you can use a pump rated for high pressure, and use a regulator that will adjust to the correct pressure.

I would recommend that you get an adjustable regulator and mount it in the engine compartment where you can adjust it without crawling under the car.

I would recommend the Tanks Inc. tank. Good tank, good price. Contact them for a pump/regulator setup. Aeromotive sells the same tank also and should have carb regulator setups too.

Or add this, dual pick up to electric pump, just a thought

i would add an oil pressure controlled cube relay to power the pump. just in case.

70 L camino, grampa engine, g-force 5 spd, road rage suspension. Pray first before all else fails.

I have a Mallory Supercomp 140 fuel pump that I have had on the car for nearly 20 years (my daily driver till 4 years ago). It is above the tank, pulling through about 6 inches of fuel line. I do have it powered by a relay. It works well.

I put an inline pump on mine for EFI(30PSI) on the frame rail.



Here is how I did the return to the tank.



Put the regulator/ return line under the DR fender.
