Questions: Will this kit work with the original fuel pump on my ‘53 M38a1?
Question By: Brian Simcoe on Nov 8 2018 3:37 AM
No, the orignal M38A1 was a dual action pump. See part number: MFUELPUMP

Questions: Do I have the correct fuel pump? On the underside, it appears to have raised letters AC and the numbers 1523039. Numbers are worn, blurry, and hard to read.
Question By: Gary on Jul 13 2017 7:45 PM
As long as you have a 4 cylinder engine and the fuel pump is a single action pump, this will be the correct one for you.

Question By: Robert Caissy on Jan 20 2017 10:25 PM
If you have the 4-134 engine these pumps would work for you. They are fuel only. If you need a vacuum you would run it off the base of the carb.
