Default Mechanical Fuel Pump Question
Hello Gentlemen, I have a 351W based block and I'm using the Carter mechanical pump. The in line fuel pressure gauge is now reading about 2.5 - 3 pounds. My older gauge was not liquid filled (it also started to have low readings) Several months ago I changed over to a liquid filled gauge and it was reading 4-5 pumps but not recently. I have a new fuel filter on the car.

The question: If the mechanical pump is the culprit, do they fail
completely or do they slowly fail and die giving one fuel pressure
from 5-6.5lbs (new) and then progressively lower readings untl
death.....

Thanks, Mike Sharkey
