Fuel sending units
My gas gauge has not been working for awhile. I decided to have the sensors replaced and was wondering if I needed to replace the pumps as well? I sure would hate to go to the trouble of dropping the tanks and down the road have a pump go out. The car has 110k and sure don't want to do it again. Can you tell by just looking at the pumps? Oh its a 2008

Man if I was gonna go through all the work to drop the tanks I would surely replace the pump..the pump either leaks or it doesn't looking at if it's working won't show much but if your there for the cost of a pump I would replace it.
Kinda like when I had my tranny fluid and filter changed I had them through in a new tranny cable not that anything was wrong with mine at the time but you never know., plus I have that kind of luck........

Replace the pumps for sure while you are in there. With all the labor involved in these things it's a no brainer. Just FYI, there is another thread on here about a guy who just plugged a 2 resistor voltage divider into the harness in place of the sender that usually fails first to fool the CPU and get rid of the CEL. The right hand tank I think. IIRCC it then always reads 1/2 full until it actually gets down to 1/2 full and then reads correctly.
