Hey guys, I noticed when I was driving the GTP yesterday to put gas in it that the gauge jumps around for some reason. I was stopped at a light on flat ground and it went to full, then slowly came down to half. It does not move constantly but you know its not right. Anyone have any ideas on what this could be???

A sender huh, is that hard to put in. Do you have to drop the gas tank? Is there one I should get or will any do??

Not hard to put on. You don't drop the fuel tank. You can get to the fuel pump via the trunk access panel in the rear seat. Left up the carpet and you'll see the compartment door. I advise you to clean thoroughly the area from dirt. You don't want any gunk to get into your tank. Unhook the fuel pump, be cautious of any excess gas so bring a small tub to put it in, take out the sender. Insert the new sender and re-install.

What mileage do you have? If it's high, have you considered installing a new fuel pump w/ sending unit?

It's an easy job. If it's a high mileage car you might just consider swapping the entire fuel canister. It's easier and might be cheaper, depending on what senders cost. We have the whole canister, brand new for pretty cheap. It's probably our most popular item now that these cars are all old and stuff. :)

The car has about 136k on it, the motor has about 40k. I will look into just holding off a little bit and changing out the pump then. Do you guys thing I would need one of those race fuel pumps

Junkyard is your friend..

i saw a TON of 98+ wbodys there.. which have the 40-240 ohm resistance sender... (i was searching for the 0-90 ohm for my 97 GTP)

Get one and ill throw it in for you on the cheap

(just take out the canister, and cut the two purple wires... detach from the canister, and purchase.)

you can also disassemble the connector at the top relatively easily and not have to cut the purple wires.

no soldering or anything.
