peteretep Posted August 10, 2005 Share Posted August 10, 2005 what fuel pumps do you guys use?? standard or performance, also does anyone use a fuel regulator? im thinking of using an uprated pump on my 1600 xflow Quote Link to comment Share on other sites More sharing options...
SYKOV6 Posted August 12, 2005 Share Posted August 12, 2005 im using a carter hi flow mechanical . bolts onto the engine in the original place and pumps 120gph@ 7psi rather than 90gph@ 4-5 psi of the stock pump. prolly right on the verge of having to have a regulator but havent had any trouble so far.[touch wood] Quote Link to comment Share on other sites More sharing options...
RT Posted August 12, 2005 Share Posted August 12, 2005 I'm running a 450hp Bosh high volume high pressure pump.. mounted above the diff and a rising rate pressure regulator off a madza 4WD turbo Familla.. Quote Link to comment Share on other sites More sharing options...
peteretep Posted August 12, 2005 Author Share Posted August 12, 2005 damn 7psi is alot isnt it? i suppose your cars a drag car though, in the burton catalogue it says that I should need no more than 4psi. I was looking at maybe getting a facet silver top pump which is 4.0-4.5psi Quote Link to comment Share on other sites More sharing options...
SYKOV6 Posted August 12, 2005 Share Posted August 12, 2005 yeah i was a bit worried at first but holley carbs are quite heavy duty and it has a top quality needle and seat that seems to seal the flow ok. any more psi and i would b needing a reg Quote Link to comment Share on other sites More sharing options...
