BreakDave - GT Posted November 30, 2006 Report Share Posted November 30, 2006 what car this goin in mate? i have seen it done on k series corollas where the original fuel tank gravity feeds a approx. 2L surge tank that sits in the spare tyre well. the surge is fed by short piece of inch diameter hose from the tank, and an external pump draws from the surge, with the return lines also goin to surge.

Jason Posted November 30, 2006 Report Share Posted November 30, 2006 i would deffinatly run a lift pump, i wouldnt rely on gavity to feed my blown motor Quote Link to comment Share on other sites More sharing options...
BreakDave - GT Posted November 30, 2006 Report Share Posted November 30, 2006 well the beauty of that set up... without the lift pump... is that u don't need a lift pump lol ie cheaper.... i'm sure u would ever run out of fuel with it either, ie in cornering.

BreakDave - GT Posted November 30, 2006 Report Share Posted November 30, 2006 the gravity feed has worked on 400hp circuit racing cars no probs and i doubt u would have as much corner speed as em to cause fuel surge! Quote Link to comment Share on other sites More sharing options...
Des Posted November 30, 2006 Author Report Share Posted November 30, 2006 (edited) I'm trading some of my ke/ae parts for a vl lift pump so no loss if i use one or don't. Edited November 30, 2006 by too quick Quote Link to comment Share on other sites More sharing options...
camerondownunder88 Posted December 1, 2006 Report Share Posted December 1, 2006 Gravity feed might work but a high pressure EFI pump run dry for a second or 2 cooks em I have killed abotu 2 VL turbo EFI pumps now due to this..lol . The vanes on the rotor ar rubber and well at there max pressure bend a bit and act like an internal by pass so when dry you melt rubber so I would run a lift pump to be safe. Will you need baffels installed into your fuel tank? Cameron Quote Link to comment Share on other sites More sharing options...
Des Posted December 1, 2006 Author Report Share Posted December 1, 2006 I wont need baffle if i have a surge tank, Carby tanks have no baffles or small ones, EFI tanks have bigger and better baffles. Quote Link to comment Share on other sites More sharing options...
Medicine_Man Posted December 1, 2006 Report Share Posted December 1, 2006 Make sure you run EFI hose on the pressurised side of the system, Low pressure lines like the lifter you can get away with standard hose. Aslo 1.5L would be the sweet spot for a 4AG(Z/T)E motor for a surge tank. When it comes to the fuel lines, Apparently they are good for around 200RWKw with a decent surge tank setup. Get the brass end fittings off Anthony Kellam to adapt the fuel lines to take the right size EFI hose.. Quote Link to comment Share on other sites More sharing options...
Des Posted December 4, 2006 Author Report Share Posted December 4, 2006 1.5 litre sounds abit better for size. I was chatting to teddy last night and we talking about were abouts to mount the surge tank, We gathered that low and more mid mounted is better for handling but i don't want it in the cab with me so what are peoples opinions and suggestions ?

Raven Posted December 4, 2006 Report Share Posted December 4, 2006 To pass road laws here, you need to have the surge tank mounted under the car in a KE70 as the fuel tank was never fitted in the boot. Quote Link to comment Share on other sites More sharing options...
Des Posted December 4, 2006 Author Report Share Posted December 4, 2006 I want it mounted in front of the diff and not in the cabin so I'm quessing it will go under the car but i will be going off road and i don't want it ripped off half way out to bumf**k Quote Link to comment Share on other sites More sharing options...
Jason Posted December 4, 2006 Report Share Posted December 4, 2006 (edited) Well I wouldn’t want an aluminum (assuming that what it’s made out of) fuel tank under my car. If you wanted better weight balance..... It only ways f@$k all even with fuel in it, so just mount it in your boot unless you want to carry heavy stuff. IIRC when i was talking to some road worthy guys the boot is 'sealed', but even if you have trovble getting it passed you can box it in to one side. Need a picture to show what i mean, i don't mean box it so the fumes build up. Edited December 4, 2006 by Jason Quote Link to comment Share on other sites More sharing options...
love ke70 Posted December 4, 2006 Report Share Posted December 4, 2006 as you are using a lift pump, why not have the surge tank in the engine bay, along with the efi pump. no need for it to be lower than the tank if using a lifter Quote Link to comment Share on other sites More sharing options...
