fuel guage sensor.

my '06 Trailblazer has apparently blown out the fuel guage sensor. it was erratic then stayed on "E' for two months. So I get to drop the tank to check it...unless someone knows how to check it easily. So I'm figuring if I'm going to drop the tank maybe I should just get a pump and sensor replacement. It has 150 k. Feedback on this would really be appreciated since I'm gonna shade tree this. Ken

I put a fuel pump in mine at ~140K just because I figured it was due; and I didn't want to be stranded as we had a cross-country trip in the near future.

Yours will be more expensive because you're replacing the whole in-tank assembly rather than just the fuel pump--but not any more labor.

While the tank is out, you'll want to verify that the wire harness is in usable condition, and that the gauge works properly when you manually move the in-tank float.

I'd replace the pump/gage module, try and use oe parts.

I found the OE fuel pump assembly here (http://www.gmpartsonline.net/parts/2006/Chevrolet/Trailblazer/LS?siteid=215055&vehicleid=186821&section=FUEL%20SYSTEM&group=FUEL%20SYSTEM&subgroup=FUEL%20SYSTEM%20COMPONENTS&component=Fuel%20pump%20assy). I'm not 100% sure if it's both the pump and sending unit, but pretty sure.

thanks for the input guys
