So my gas gauge is officially stuck on full.. anyone know what the problem could be and how to fix it by any chance? 01 RS with 03 WRX swap so the fuel pump is from a WRX everything else, im sure, is from the old fuel system.

 

ok here's the deal... the way your fuel gauge works is on weight and on a sensors that travels on a conductive surface based on the amount of fuel you have in the tank.

If that surface of the conductive surface is dirty it will not register with the sensor. what you should do is pull your fuel pump completely out of the car. check if your filter is dirty for the fuel pump and replace it accordingly. also replace the one in the engine bay if you haven't done it already. make sure that the sensor area is clean and not soiled.

make sure that you install the fuel pump correctly so that the arm that floats on the surface of your fuel can move. If the fuel pump assembly doesn't sit nicely inside the fuel tank then it's installed wrong.

Thanks Jon Ill have to check that out.. I just changed out the fuel filter in the engine bay a few months ago so I will have to break open the back seat and go for the fuel pump I suppose. Maybe its time to change to a walboro

 

Also, you may need to check your electricals if that doesn't work...I have the wiring diagrams somewhere on CD.

 

on older cars, to fix this problem is fill the tank up, then bounce around in the back of the car. sounds dumb but it does work.

 

bottomless gas tank!! no more worries about high prices at the pump lol
