ok i decided to run the supra fuel pump on my setup which flows 290 at like 14volts, and i have two ways to get my pump to flow that much one is the Kenne Bell Boost A Pump http://www.kennebell.net/acces...p.htmand the MSD Fuel Pump Booster which is herehttp://www.msdignition.com/fuel_7.htm

i am inclined towards toe Kenne Bell but i am open to suggestions also the supra pump does 255 stock iat 12 volts i believe

Check out FA.There's a couple of threads on them.

The 752whp underground car threadSurge tank setup thread (Don't even think about one of these, I know you will LOL)Walbro thread.I even posted up some good info.Check it out.

Also you would route the in paralell (side by side).Opposed to one feeding the other.You would need to get a Y valve or junction or you could run two lines to the front, two z32 filters and have a custom rail with twin side feed and center relief.

they use fuel sumps. basically a little container. your in-tank pump fills it up and just circulates back in. you then have your 2 outlets near the bottom going to inline boschs. then returns to the fuel sump.

so imagine a container with 2 basic inlet/outlet for your stock pump. then 2 outlets to dual pumps, and a return. i got a lil diagram on other cpu ill upload when i get on it

Hey can you post that diagram up I don't get what your trying to say.

Are you talking about a Surge tank/Swirl Pot?

He can just run them in parallel to a Y adapter/connector to a single line.Or he can run two lines to the front to each side of a 3 port rail.

afer doingsome research i decided to use walbro 255 intank and bosch 044 as a inline directly after seeing your diagram i think that should be efficient for my horse power range at 5~600ish, i did see some people did the 044 as a intank setup but i think this way will be safer

Why don't you use them in paralell?So that if one craps out you still have the other pushing something.

Plus you don't need a Surge tank do you?Just more $$ to spend and more things to go wrong.

the surge tank allows u to run the inline. also helps with sloshing.

the gtr aussie guys like to use that for that reason.

u could hypothetically strap 2 walbros next to eachother in tank with a clamp then Y them together. i know supra guys do that (even up to 3 walbros) but they have these nice holders designed for that.

We did two Supra pumps in my boys evo with Metal straps, to the stock bracket.

Los the easiest thing to do it run them paralell.If it works for the Supra guys then It'll work for you.

Don't over complicate your car.It'll just take longer, cost more $$ and you'll never get to drive it.
