Electric fuel pump- not IH, but it's red!

Hey, gang
I have a 75 cfm air compressor run by a small 4 cyl Continental
flathead. It had an electric fuel pump on it when I got it. It
worked, but was getting temperamental. Finally one day it quit. I
figured that "it was it"s time". Got a new one at auto parts store.
That one lasted about 2 hours. @#$%^ cheap junk, I figured.
Took it back and exchanged it for a new one. That one lasted
maybe 10 -15 hours and died. I"m beginning to think that it"s
more than coincidence.
So- what"s killing my fuel pumps?
Is it just @#$%^ cheap junk?
It"s the electrical part that fails. After they quit, you can hear it
click whenever you turn the ignition on, but that"s it. No happy
little chatter that a fuel pump is supposed to make.
How do those work anyway? I assume that it"s just a solenoid
with power turned on/off rapidly, connected to a diaphragm
pump. It seems that whatever makes it pulse is not doing it"s
job.
12 volt system, negative ground, with a Delco 10SI alternator.
The pump is grounded well- even ran a dedicated ground wire
to the battery to see if that would help.
