When do you replace a mechanical fuel pump?

How can I extend the life of my fuel pump?
There are a few ways that the average driver can extend the life of their fuel pump with very little effort: Always keep the tank at least a quarter of the way full. Gas acts as a coolant for the fuel pump, and if the tank runs dry then there is no liquid to cool the pump. Overheating shortens the life of the fuel pump.
Where can I get a new fuel pump?
After calling about 8 different places, I finally found a new fuel pump 100 miles away on Saturday. Went and picked the pump up, put it on and thought all was going to be good. Well the fuel pump worked, but then the shift connector for tranny cable broke. This was somewhat of an easy fix, but will be ordering a new connector today.
How can I check if my fuel pump is working?
Before you check your fuel pump, find the fuse that corresponds to the pump and pull it out to see if it is broken or burned. If it looks fine, check the voltage at the pump itself to make sure the charge that’s leaving the fuse gets to the pump. If this looks alright, then perform a fuel pressure test.
