Dudes,

My Gas needle just went nuts, some times it,s ok, othe timer jus flat empty and most of the time bounce all the way, even with tank at full!!!!!

Here the wana sell me the whole ansembly ($800) caue they don't have the sensor apart.

Can anyone tell me the part number for that sensor, cause I have this friend that is going to miami on thursday and comming back on sunday, so I want him to bring me the replacement.


Can any one help me please?

ttt for ya, I also know someone with the same problem

trace the wires. Sounds like a short or bad ground.

Mine started acting strange lately too. If the truck idles, or sits stationary for any length of time, the gauge drops to empty. If I shake the truck, or accelerate, it goes back to the correct fuel level.

Anybody have this before? I'm thinking it's a problem with the float, or the sending unit in general.

I'll recheck the wires today REDHEART, and a leak on the left header to send some logs to Allen

Very common problem. It's the sender in the tank. I have replaced several fuel pump assemblies for this problem. You said you replaced the pump but it sounds like just the pump not the housing that has the sender on the side of it. The sender can be removed from the pump housing but I don't think it's available without the pump assembly.

That sounds like the sender. It is available from GM, but it is around $180 or so I am thinking. I can check tomorrow.
Like Chev5.3 said, score a whole setup off ebay for $150 or less. Cheaper than the GM sender and you get a free spare fuel pump!

Yur right guys, I changed the punp, but not the housing.

Check the housing by the NET

Thanks dudes
