I had to take my truck to the dealer to get a few things taken care of that went bad soon after i had bought the truck.

Now some history, i bought the truck used from the wholesale lot at Humberview. No extra warranty or nothing. Just the truck. i went and told the dealer about this last week, and they ended up taking care of it at their cost.

1. my gas gauge went out, about 2 weeks ago. Every time I would fill it up, it said it was empty hahahaha. And take a lot of driving to get it to come back to normal operation.

so they r gona drop the tank, and replace what ever they have to. Ill know when I pick it up.


I dropped it off this morning 10:30am, its done now 2:35pm, so ill be leaving in a bit to pick it up.


I am interested to find out if they had to replace the whole fuel pump and sending unit as a whole, or was the sending unit a replaceable part?? Why? because a brand new fuel pump and sending unit would be good for another 100k(ish) instead of worrying when the one i have will go, hahaha.

The reading i have done tells me that since i have an 05, my fuel filter is in tank, where early models had an external fuel filter that they could service. the in tank filter cant be serviced because its part of the pump (i made sure to ask the to flush the tank and check / clear debris since they had to drop the tank and it was basically empty anyways) and that the sending unit was part of the pump unit as well. if they are 2 seperate pieces, then it will be cheaper to service my self if i have to in the future. where as if its all one unit, pump /filter / sending unit.....its nearly 3x the price!!

As soon I get my truck home, and talk to the guy in the shop. ill let you know what exactly was done, and ill get some part #'s if possible.




I hope this will help some people diagnose, and answer questions about the intank fuel system.


cheers :),

**UPDATED**

Ok so they looked over the fuel system, and the problem was the sending unit.
the GM "FP Part #" - 19177712

the sending unit kit Part# - "Sen Kit N" 031070

The stepper motor is fine, cause the gauge works soo much better now. It goes up to the right level way faster then before the repair, even when the gauge seemed to work fine right when i bought the truck.

In the end. So far i am very happy. Kinda wish i got a fuel pump though hahahaha.
