Fuel Filter ?

kaneak2002 · June 13, 2007

I havn't spent any time looking, but just curious where the fuel filter is on a 05 GMC 2500HD 6.0. and do you need any special tools to change it?

In the tank.

It is in the tank as a unit...(pump, sensors, filter) The filter is for the life of the vehicle.

So how long do they really last? A buddy has a 02 6.0 and he has had to replace the fuel pump twice in two years. Have they improved them or are they the same one. It kind of seems strange not to have an external fuel filter.

There is no way to answer how long the pumps last. Some go forever, some go in a couple years. Don't worry about it. The "sock" in the tank is not that strange. My wife has a 2000 Honda with that setup and there is no problem with it clogging.

One variable is how much crap additives, fuel cleaners, etc does your buddy use....two things can contribute to early failure...

1. constant use of fuel cleaners i.e. every tank....

2. letting the fuel pump run hot with a low tank volume frequently...

The fuel additives errode the coating off the windings as a solvent and running low fuel all the time i.e. less-than 1/8 of tank is bad...as the fuel cools the pump.

Keep your tank up, and use additives only when necessary i.e. every 6000 miles or oil change or whatever rather than every tank...

If you buddy did neither of these, then I'd say it's just fluke cause they should easily last 100K

I'm not real convinced the runnig a tank low will cause premature failure. 2 reasons for my way of thinking. 1st the pump sits in a resevoir. You have to pretty much be empty for it not to have any gas around it.

2nd the fuel being drawn up thru the fuel pump cools it also. So if there's gas well in theroy the pump is being cooled.

what was it the late 90's early 2000 camaro/firebirds that the pump would go out almost every time the car ran out of gas? There is not very much fuel in the pump itself to act as a cooling agent, maybe a quart, but if the sender is surrounded by fuel thats alot more area to disperse the heat.

just my .02

He doesn't run any additives, just uses chevron fuel 90% of the time. He used to run his tank low, but doesn't anymore.

I also had heard this about the fuel running low killing the pump so I asked the service tech where I bought my truck. He said the fuel lubricates the pump, dosen't cool it.
