i have a new set of 780 hp , blown 500,s going in a cig . i want to run mechanical fuel pump's . what pump do you guys run on your boats ?

Holley 170 GPH ... Summit racings part number 12-454-20 . Running them on a pair of blown 496's dynoed @ 765 hp . Pumps maintain pressure with no issues .
you have to drill and add a small tube nipple to the pump housing for marine use .

I love my all billet rebuildable CV products mech pumps.

thanks for the anwsers !

Kenny, I have similar power. I run the old fashioned six valve marine pumps. They have 1/2 NPT in/out. Self regulated. They work nice. Holley stopped making them a couple years ago, and now only offer a similar pump but with 3/8NPT in/out, or the billet pumps.

PM Mike Tkach here. He might have a pair of Holley Ultra Billet pumps, Teague Fuel log, twin regulators, the whole setup for you. He's switching to a totally different setup. (1200+HP). Maybe you can work something out with him. All his stuff is less than a year old and prob 20 hours on the stuff.

i have what he needs,and will sell at a fair price,this system is to small for my 1200,s,but perfect for 1000 hp or less.
