Where is the Fuel Filter on a 2006 Lucerne?

[RoadBastard]

Having some fueling problems but cannot seem to find any information on where the fuel filter is off all parts.

If it is like my Lesabre, it will be located on the underside ahead of the gas tank. It was pretty easy to change by backing the car up on ramps and crawling underneath. Kind of messy to change with the gas that will get spilled.

Thanks for responding Irish. I found out today that the Lucerne does not have a fuel filter. Isn't that crazy. Instead the dealer does some expensive fuel injection cleaning service.

It has a 'non-serviceable' fuel filter built into the fuel tank.
The injector cleaning procedure has nothing to do with fuel filtering but carbon deposit growth on the injector. They two aren't really related.

What are your 'fueling' problems?

Serviceable by the dealer. If GM could figure out a way, putting air in the tires would be a dealer item.

Serviceable only by replacing the entire fuel pump/sender module assembly to the tune of 500+ dollars.......non-serviceable if you ask me.

Anyone try and add a fuel filter?

Seems like a simple solution assuming the pump can handle the extra resistance.

That would only work if you removed the one in the tank. Otherwise, if contamination got in your fuel it would still get trapped by the in-tank filter and never make it to the one you added. Plus you run the risk of catching fire when your cobbled together fuel connections give way.

Catching fire? Use fuel fittings. Problem solved.

...and you totally ignore the fact that it was a pointless suggestion?? awesome.

Not pointless. Remove the in tank filter. Or put a secondary filter on that has a higher micron rating, thus protecting the expensive injectors.



Or like you, you can just sit there and hope everything works out fine.

Ya, I agree...non-serviceable in the usual sense... but anything is serviceable at the dealer, if you want to pay the bucks. You missed my point entirely, which was GM (and the others) are making it more and more difficult for DIYers. In years to come, we probably won't be able to do a simple brake job ourselves. Pads will come as an assembly, with rotor, caliper, and perhaps even the drive shafts, and you will need special GM tool J-456743V1 to install it. Progress my azzzzzz. It is just stupid to have to go to the dealer (or even DIY) and have a perfectly good fuel pump/sender replaced because a $1.49 filter is clogged.

What do you mean? It's a complete fuel system cleaning service. The fuel that goes from your tank to your pump through your lines, through your fuel rails, into your injectors and sprays out into your open intake valves to be burnt up is all apart of the same system. You can get debris and other accumulation into you fuel lines,fuel rails, and injector fuel inlet ports. Even fuel injectors have filter screens to weed out the stuff that gets by the filter. These cars are a pita because they don't have an inline fuel filter to change out. You have to purchase the complete pump assembly. How reliable is it who knows? Either GM managed to eliminate the problem of fuel contamination or are they just trying to get you to purchase an even more expensive part when it goes. I say option two.

I'm going to go with option B.

That's why they went to the computer to control the motor and all the sensors in order to make us take them to the Dealership to get serviced. I was told when it first came out to get better gas mileage and I didn't believe that for a big when they don't get any better mileage. Dealership's was loosing money cause people knew how to work on their own vehicle.

Fuel pump and filter are all one component, no owner service possible than replacing the fuel pump.
