If its electric its in the fuel tank. Depending on where you live the sending unit may be in pretty rough shape. Also the older GM's are pretty well known for burning up the terminals in the connector on the inside of the sending unit. So even if you replaced the pump the sending unit could be bad and the pump could still not work.

Where is the fuel filter canister located on this 2006 GMC sierra 1500


The fuel filter on this vehicle is located inside the fuel tank and is a part of the fuel pump module. As such, it can only be serviced by replacing the pump module assembly. In theory, these are a lifetime filter and I've only seen a couple of them plug so far and those were due to dirty fuel that came out of a private service tank. The only real test to see if the filter is restricted is to have someone road test the vehicle with a fuel pressure test gauge hooked up to the fuel rail so the actual pressure can be observed while the vehicle is under load. Hope this helps out!

Hiw do you replace the fuel pump in the gas tank of a 89 gmc suburban?


you'll have to unbolt and lower the gas tank, removing the clamps for the filler neck and vent, also unhooking the fuel pump wiring and the fuel lines. it works best to run it as low on gas as you can; the tank is much easier to raise and lower when it's not full of gas. once you get it down, you'll see that there is a lock ring that you have to use a hammer and punch to rotate counterclockwise to unlock the fuel pump assembly from the top of the tank. Put the new one in as you took the old one out, and return the tank to its original position, hooking everything up as you go. put Fuel in it, and you should be good to go.
