My blazer has a replaceable fuel filter along the underside of vehicle by driver door, as well as a filter at the pump assembly. It eats fuel pumps at least 1 every other year since 95. Lifetime warranty came in handy, but install fee has kicked my ass. I would have liked that blazer if it wasnte for fuel pumps and brakes. |
cleaned of sediment? Fuel pumps are usually good for 60,000 on the very low
side, but more commonly, 100,000 miles. I can't blame your for not liking
that maintenance record, but I'd be looking deeper into the causes. That's
*not* typical.

Almost all of the vehicles I've seen built in the past several years have a fuel-tank-mounted fuel pump and even the asian cars and trucks suffer from the same issues. In fact, my wife's non-domestic SUV uses an in-tank fuel pump that has an integrated fuel filter that is non-replaceable (talk about cheap!), but it's waranted for 100k miles. The units that have replaceable fuel filters I believe have a better filtering ability, but that just emphasizes the need for regular filter changes. A combination of letting the filter go too long between replacements and running the tank low will wear out any fuel pump regardless of maker.

Did you ever replace the gas tank or have it cleaned of sediment? Fuel pumps are usually good for 60,000 on the very low side, but more commonly, 100,000 miles.

Because people don't change their fuel filters at the 30k interval like they should. Add running the tank down to fumes to the mix and voila......... -- John "anything you say can & will be misquoted & used against you" |

levels causing failure? I run for days on fumes. Been doing so for
decades. Haven't had fuel pump fail yet (knock on wood)!

Where are you getting your pumps? Never seen them fail that fast unless they are junk out of the box. Might be time to look at other issues, like bad ground to the pump or low voltage, also do a flow rate test and see if there is something else as a contributing factor. -- Steve Williams |
and may not be easily found. Only a flow rate test will tell you one way or
the other, but I would also check fuel pressure as well. A dirty ground is
also a possibility, or perhaps a dirty harness connector as well.

I can see the fuel filter causing strain on the pump, but low fuel levels causing failure? I run for days on fumes. Been doing so for decades. Haven't had fuel pump fail yet (knock on wood)! |

Fuel cools and lubes the pump internally. Pump running dry on the curves and turns, even for a split second, will shorten it's life. Running out of gas is the worst for the pump.
