CIS fuel pump.. differences 2.7/3.0?
I need to buy a used fuel pump for a 2.7 CIS engine and was wondering if there is a difference in the pumps between the various engines? There are a couple on ebay, one is for a 2.7 (a '74) and one is from a 3.0L engine. My engine is a '77 2.7 so I'd rather use the newer pump (3.0L) if they are the same, otherwise is the any difference between the '74 and '77 (2.7)?
Thanks for all info! Doug C |

doug, use the pelican parts catalog and check to see if the part numbers are the same.

3.0 puts out more volume as I am told at top range. My conversion from 2.7 to 3.0 never changed the pump but most said it would only change WOT fuel volume. I have yet to see a problem

As part of putting a Carrera 3.0 in my 74 Targa, I had the same question. Looking it up in a parts manual, the Carrera 3.0 has the same pump as the 2.7L. With that I did not change the pump. I will let you know what my WOT acts like after I get the thing started and broken in.

Looks like '77-'79 cis pumps have a different part# than the rest. My engine is '77, but do you guys think there's any real difference?

the real difference is volume. a 3.0 will require more volume than a 2.7 but should still work I think pressures will remain the same
