Hi all, so we've got a 1987 4207 with twin 7.4 Crusaders
Port fuel pump was getting worse, so decided to replace both
Ordered the Carter 97843, flange number 60502
Long story short, we ended up ordering three of these and all three are going back to the vendor
Original Carter pumps lasted 35 years...they have a brass alloy arm with a visible spring under the arm
These newer pumps have no spring and are black steel arms
Each of the arms would get pushed by the pushrod until they bent just ever so slightly...like just enough that the pushrod would run out stroke to the point that they were not able to literally get enough pump diaphragm movement
So, here we are with 3 faulty pumps.
Problem is, trying to find a different one that I know for sure will work.
I know some folks have done the electric conversion and I'm not a fan of that route as I believe in the mechanical pump since it's worked for so long with no issues
Please chime in with what pumps you've had tremendous success with!!
Thank you
