Need some help with a cis 8v
Dave;
CIS-E versions do have an external FPR. its rated at 5 bar. I know because
I was going to use one. The audi version is CIS has a very strange
external FPR.
Early CIS version do have an FPR is just on the output side of the fuel
distributor, also rated at 5 bar +/-
An 89 cabby I *believe* comes with Digifant so there should be electronic
fuel injectors and an FPR on the end of the plastic fuel rail.
