It defanetly sounds like a sending unit and the fuel tank needs to be removed in order to replace it and it will most likely come with a new fuel pump too.They come as a unit and there not cheap. Sorry.

Speedometer fuel guage


Probably replacing the speed sensor on the transmission.Have the codes read, even if the light is not on. Look at the pending codes. The fuel gauge would be the sending unit in the tank. That act funny like that sometimes.

When my fuel tank is full the guage registers empty


Could be a problem with the gauge in the instrument cluster, or the wiring that goes back to the tank, or the sending unit in the tank.
The sending unit has a float much like your toilet which could stick or fail to move.

Fuel guage always shows empty


It sounds as if the fuel tank sending unit is faulty. This is a small float connected to a variable resistor on the fuel pump/sending unit assembly. Unfortunately this assembly is fairly expensive (over $300) and the fuel tank may need to be removed to replace it.

How to change fuel pump 1990 cadillac seville


The fuel pump and sending unit is located in the tank. I hope your tank is empty, if not you will need to siphon it out. It is dangerous with the gasoline, and remember the fumes burn, not gas. You start by removing the filler hose, then loosen straps, detach sending unit wire and fuel line, then lower tank. Then unscrew the sending unit/pump and replace. reinstall.

Erratic Gas Gauge


You need to remove the tank and replace the fuel pump as the sending unit is part of the pump assembly.

Car bogs down when given gas.


Hi there,
This problem is most commonly caused by a weak fuel pump. It will need to be checked with a fuel pressure guage. If you can obtain a fuel pressure guage you will need to observe the fuel pressure while accellerating to see if it drops out.
good luck
