Thread: BBC fuel pump question

Tweet

Maybe Pat McCarthy or one of you other member could give me some advice to go on a BBC fuel pump? I will be running a LS6 454 with a hyd roller cam, 850 Holley double pumper, turbo 400 with 2600 to 2800 stall converter, and I am wondering as to how many gpm of a fuel pump I should be running? I want to make sure it is plenty big enough and also I want the fuel pump to be very good looking whether chrome, billet, or whatever because it is in a highly visible area. Also what size of fuel lines would you recommend to use? Thanks in advance for your help...the members of this forum have help me so much with their wisdom & advice.

I would run an Edelbrock Victor pump.
Pumps 130 gph.It is rebuildable,chrome and comes set -up with 1/2 inlet and outlet.
Yes,you will need to run a regulator with it.

yes 1/2 or 3/8 lines the vick fuel pump or the carter#m4889 well do the job. on the fuel pump run a hollow bronze tipped pump rod the carter will not need no regulator . great pump for a mild big block

Pat,good call on fuel pump push rod.
I was a sleep at the wheel again and forgot.

Pat & Eric thanks for the information. I will check into the Carter as my first choice since I do not have to run a regulator with it.

Hey guys,
Why does the fuel pump I have on my '84 454 have three connections? The motor originally had a quadrajet on it. I am assuming the large one is "in from tank", the square threaded one is "out to carb", the third smaller is a "return to tank" maybe...I dunno??? I always thought only fuel injection had a return.

I am dropping this engine into an older car with only one gas line. I plan to replace this pump anyway, not run a return or whatever that third one is. Will be using an Edelbrock carb.

here is a picture:

Right, it's a bypass to the tank. It is supposed to keep the pump moving some gas, reducing the chances of vapour lock. Sometimes it works.

So with the Carter CRT-M6901 you do NOT need a regulator because it flows 120gph and only has 5.5 to7.5psi? Whereas the Edelbrock Victor series EDL-1712 runs 130gph and has a max of 10psi so you DO need a regulator? A regulator is almost as must $$ as the fuel pump. Wonder where the cutoff is gph or psi?

I seem to be running lean with the rochester Q-Jet I have and it looks like it is fuel delivery not carb setup.
