I have a mk4 escort cabriolet, it's the rs turbo engine which has been changed from mfi to efi, I bought it as a botched up project, re wired in an xr3i loom now to get rid of the good old chocky blocks 😳😁!!. Anyway, she starts drives and pulls well, but the overfueling is ridiculous! Would the tank and pump be a problem? Meaning would I need an efi one?. Thanks Cals
