77magnum13hundy Posted August 12, 2011 Share Posted August 12, 2011 OK guys time to rack some brains I got a bosch 3 bar external pump and another pump off an 87 ish efi'd integra which is external too unsure of its pressure capability. I wanted to get a weaker pump to fill the surge tank, but is it dumb of me to run one as the lift and the other to the fuel rail, one surely will be over doing it. And then another q. what should i use as an alternate? Also running fuel line under chassis, 8mm ish steel bundy tube ok?, will it bend ok or collapse? Someone has done this before, its only for my 4age so no more than 50 psi will be needed Cheers Quote Link to comment Share on other sites More sharing options...
Shandangles Posted August 12, 2011 Share Posted August 12, 2011 use integra pump from tank to surgem bosch from surge to fuel rail, woy overkill but you have everything so who cares. 8mm bundy will be sweet Quote Link to comment Share on other sites More sharing options...
Roman Posted August 14, 2011 Share Posted August 14, 2011 You need a low pressure / high volume pump to the surge tank. Think a running hose vs a water blaster. Quote Link to comment Share on other sites More sharing options...
CUL8R Posted August 14, 2011 Share Posted August 14, 2011 Use a facet pump from a subaru leone - same as the aftermarket ones available on trademe... Quote Link to comment Share on other sites More sharing options...
77magnum13hundy Posted August 18, 2011 Author Share Posted August 18, 2011 Running the fuel lines from the boot out under the chassis.... eh anyone no what the legal requirements are for this? Ive got some line rated at 100psi going from pump to steel bundy, and one for the return line to the surge tank.... some flash people have put a unit in where the lines connect on each side but if i put a hole thru and run straight pipe out with gromment surrounding would that be enuff?

Shandangles Posted August 22, 2011 Share Posted August 22, 2011 from memory the bundy has to be "mounted" to the chassis every 300mm Quote Link to comment Share on other sites More sharing options...
