h23 prelude turbo. t3/t4 at 8psi daily driver. have stock prelude (240 or 270cc) injectors. Vortec 12:1 fmu (or whatever comes with drag kit). i want to get rid of this damn walburo inline pump cause its ugly and takes up space. i was talking to a guy at auto performance engineering and he said the 255lph high pressuer intank would still not support enough fuel. he said my fuel pressure would be over 100psi when i am boosting. what should i do?

It will hold

I beg to differ with over 100psi of fuel pressure that the 12:1 fmu is gonna make the walbro intank is not going to be able to deliver on that kind of pressure, which is why all people useing higher then 8:1 fmu's at 7psi use inlines... mabye if your only at 7psi or less on a 8:1 disc you could only use an intank pump.

keep the inline?

my walburo is an inline not intank. is there any intank that i can get that will do the job? i hate this damn inline.

rjardy

some folks will say that you can do it with an intank, but you DO NEED an inline to keep up tp the demand of the fmu.

Right...inline are high presure pumps. intanks are high flow. U need high presure inconjuction with the fmu.

Stick with the inline pump.....

What about the walbro high pressure intank pumps? Like the 255lph Highpressure..

i still dont think it will hold. unless you have tried it and works for you?

BoostedH23a1

yea thats exactly what the dude at auto performance engineering said. he said even with the 255 lph high pressure intank i would still need the inline. thanks guys. btw how do i get my 95% user rating back up to 100?

Cramerox

lol what did u do to get it that low anyways?
