What fuel pump in a 3.6 conversion?

[burgundyben]

I have a 95 993 motor in a 78 SC, its not running great, I'm still running the CIS fuel pump and its 30 years old.

What pump would you Pelicans reccommend?

Thanks.

I use the 84 and later fuel pump. You need at least 50 psi, not sure of the output of the CIS pump. I'd add a fuel pressure gauge to check before you spend a lot for a later fuel pump. Describe "not running great", might be something simple.

I've been using my CIS pump for years....

We used the original Carrera pump in a '88 Carrera and that worked fine too.

i have a couple of Bosch FP PDFs

one is a cross ref
other is FP #'s etc for all cars including the 12 cyl

one title part of a chart is listed as Cap which just might be capacity
