Never been asked this before. Even i want to know. How long does an
inline fuel pump last in a ford taurus or any other car for that matter.
Prime example. My 94 3.8 has 538,350 km on it (334,515 miles ). Pump going strong. I hope. Providing no mechanical proplems and fuel filters have been
changed regularly and no contaminated gas. Anyone have high milage stories
with an original pump ? The reason i'm asking is because i found out the pump's electric motors have com. brushes. Brushes do ware out. But when ?
They use a copper based bush as in a starter. Carbon based brushes are used
in heater motors and alternators and last about 3 years. Anyone know ? I have an old working pump but don't want to take it apart. Like i said it still
works. Any ideas just jump in.

Hello Chip:

Long time no See...LOL...Wow man you got me hanging. I think there is so many variables come into play.

I put a pump into my Escort Brand new not reman... and the thing only lasted 9 months...went and go a Reman...off Rock Auto, and it's going strong after 2 years.

Yah a forman at one of the dealers i know, that is still alive and not retired says they
can last 3 weeks or last forever. I'm not the original owner of this car. Mine. Actually my
wife's. He was saying pumps can last longer than the motor and the body. that dosen't
help with shit. When they quit it's NOW. you don't get a hint. Well the mechanical
pumping action gives you plenty of hints but the average car owner hasn't a clue of how
to read it. When the electric motor quits you get NO hint. Lorn, my dearler forman friend
says if it is the original pump and it hasn't quit by now it won't. Yes i've seen aftermarket
pumps quit every year. The Carter pump was the worse piece of shit ever made. The original ford was Walbro. If the Carter pump has " M " in the part number it was acceptable. They fixed it. I guess i'll know when it quits. Probably on the highway 60
miles from home on a frozen highway at 40 below. That is my luck. Oh yah, in the middle of the night in a snow storm and no cell phone service. and probably drunk. Well not drunk but you get the picture.

You can check them if you have a scope. Here's a pretty good article on it. Near the end of the article they mention the humps in the waveform. That's where you can tell if the pump is on the way out. http://www.motor.com/magazine/pdfs/032003_12.pdf

The pumps will work harder if the filter is restricted or if the tank is run low often unless it's the returnless system. The unused fuel is constantly run back to the tank on the non-returnless sytem and gets heated from the engine. When the tank is low, the fuel gets hotter and so does the pump causing heat stress on the pump. Thus wearing it out quicker.

I don't think it matters how much you drink, the system won't know.
