I thought that may be the case, as most later model cars, even carby ones, run an intank pump. If they do, they need a swirlpot. All you would need to do is replace the pump (or fit one if there is none) with a suitable EFI pump. If you give me the diamensions required, I should be able to match it up for you.

I have done an efi conversion (and used a lot of help from this forum). For the fuel pump, I removed the standard fuel filter, and put a second hand VN commodore external fuel pump and filter in the old filters place. At this stage I do not have a swirl pot, and havent needed one. If I ever burn the fuel pump out I will worry about it then.

If you want more info or pics, just PM me.

you just have to make sure the pump is primed, at all angles.
