just had my 2008 R1 engine delivered (cheers malc), and trying to get my head around all the wiring Etc.

but what do i do about fuel pump?

anyone got any advice on this?

cheers

my plan is to use my existing tank, with existing low pressure pump, which fills a small swirl pot with the original bike pump fitted in.

Either use the original pump or a high presure pump from a tin top. Original can be either mounted in the tank (needs tank making/modifying to take it) or via a low presure pump to a swirl pot made to take it (for road use its probably over complicated for the sake of occational starvation). I'm running with bosch pump from an Escort turbo. Easy to mount in line from any tank.

Sorry - this is turning into a thread hijack...

MK9R - Do you need to change your lines or have you got high pressure ones already in place?

I've been told that you can use a self regulating pump from another bike. Since I've got a ZX12-R pump of the correct sort and an aluminium flange to suit that's what I'll be using. I'm planning to borrow Procomp's fuel tank design, assuming that there is enough room in front of the axle.

have you got a return line on the fuel or is it self regulating?? I've been told the 5VY pump is not self regulating so needs a return, is this correct?

BTW, my engine arrives today

so i can have an external pump as long as i have a return back to the fuel tank?

if so what pump is recommended?

as i would rather this than fit one in the actual tank.

Any problem with Adi's suggestion?

just read it again, and am i right in thinking its a case of:

a low pressure pump (escort turbo?) in the fuel line, then a swirl pot by the bulk head, then into the injectors?

and is a swirl pot like this fine: http://www.demon-tweeks.co.uk/Product.do?method=view&n=1544&g=6303&utm_source=Google&utm_medium=Base&utm_campaign=Motorsport />

ok so i don't need the swirlpot unless racing.

so will this pump be fine? FORD ESCORT RS TURBO ELECTRIC PETROL FUEL PUMP NEW on eBay (end time 25-Oct-10 23:04:22 BST)

as i take it the regulator in the fuel rail will make sure its getting the correct pressure?

cheers

Yes, thats what I've got.
Mount it as low as possible as they don't like to suck fuel so gravity feed helps. Put a small filter between the tank and pump to stop any debris from the tank getting in and then after the tank I've got an in-line filter from an injected Astra, which has a push fit each end.

cheers, also just checked the fuel rail has a pressure regulator, is this it?





also this black box? am i right that it has the input from the fuel pump on the one side, then the one input on the other to the fuel rail, then the other back to the fuel tank?
