fuel return too small?
wondering if a small fuel return is gonna be a problem or not. Im gonna be running a in tank walbro with an inline walbro and wondering if it will be a problem using the stock fuel return lines.

Re: fuel return too small? (a1320addict)
if you have a problem, you should see it here:
static fuel pressure + boost increase
should be there solid and not go up unless boost goes up. ex:
45 psi static plus 15 psi = 60. no more
if it goes up and boost goes up, normal
if boost stays solid and fp goes up, restriction.
if it does, then there is a restriction in the return side.
i used to run 2 bosch's on a stock buick return line which is 8mm.
it is late, and i am tired, please correct me if i am wrong.

ok so I can just watch my fuel pressure gauge and see if its going up more than my boost is going up? say I hit 5 psi boost and my fuel pressure goes up 10psi, theres probably a restriction?

Fuel Pressure is about 2-10 psi after Boost, After about 1k miles with turbo I think boost killed my
