Default fuel pump

i tried to use the search but it didnt help me very much. what was the name of that good fuel pump we were talking about a while ago? racetronix or something? my mechanic thinks my fuel pump went out and i want a high flow one for future mods. anyone have a clue what im talking about?

I got it from Tpis the 550 hp one pretty big size for $180
i thought of installing but it was look complicated so a mechanic
did for me charge $150 little pricy but lot of work atleast on mine, just did installed 2 days ago at the same time installed
cyberdine digital fuel press and A/F ratio too runs like a champ
iam really enjoying this new motor still some tweaking left though.

if you install a high flow aftermarket pump do you have to get a adjustable fuel pressure regulator? will it pump to much if the motor is close to stock? i have plans for serious mods next year so thats why i want a high flow pump since mine is shot anyway.

Racetronix will answer your tech questions via email. sounds like you want/need the 255 L/Hr unit. The kit with Walbro 340 machined unit is $129.99 - a pretty damn good deal if you ask me. I just bought the 255 LHr upgrade, looks like a nice kit indeed. I'm very happy.

is that model specific?
is it a direct replacement for a stock?

and as asked above, is that overkill for a stock motor - and would a fuel pressure regulator be necessary?

check out: http://www.racetronix.com/RX-C44-FPKG-2.html

the direct stock replacement is the 190 L/Hr one, RX-C44-FPA-A kit for $99.99. this is the one you'd want for a stock LT1 engine as for a FPR, unless you need a new one, your stock unit should be fine
