Next job in the Coupe is the EFI fuel system.

Here's the kind of idea I want to go with, mounted internally on the boot floor of the coupe - rather than externally.






















It needs to feed a tuned CA18DET on the race track - so have a couple of pump decisions to make.

I'm thinking of going Carter for the lift pump as I think it can handle being mounted above the level of the fuel tank...but I'm not sure of the flowrates and pressures to use. I am thinking a Carter silver which is 100gallon/hr, 6-8psi should be the go.

Is a Carter Black 100gallon/hr and 15psi overkill?

Then I was planning to run an 044 Bosch EFI (save me ever upgrading again).

And about a litre of surge tank....

For those of you with CA18DETs with some mods (who also maybe race them) - what have you found sucesssful / unsuccessful.

I think the carter silver and black are actually the same price - but I'm also not sure if more pressure could actually be a bad thing in the lift pump.
