I noticed recent that my fuel gauge is acting up. I have dual tanks on my stock 94 302. I put a few bucks in gas in it earier. The gauge read full.. I knew it wasn't full because the tank was empty or so the gauge read empty. I get going down the road and I'm at half a tank (1 block away) and stop at the light and im at 1/4 a tank. I know the tank is full becuase when i beat on it with my hand its a solid thud sound. I only put 10 bucks of gas in.

Now my question is sender for the gauge is that built into the fuel pump or can I replace that sperately? If its the pump is their a cheaper place to get one thats not 150 bucks? I want to go ahead and replace both while I'm at it if possable.

Also is their any extre precations that I need to take care of? I know to disconnect thte battery before tinkerign with anything. Also I know do anything that make sparks/ingnite the fumes. I plan on runnign the tanks damn near empty before I attempt this. I know it will make it slightly more dangerous due to the fumes, but I dont want to mess with the liquid weight as well.


I will have to run the front tank dry first... which might tank a month or so. I don't drive the truck much at all. I can at least do the rear tank first beings that its bone dry at the moment.

 

A lot of guys doing that job would prefer to lift the bed off. If you go that route the weight of the tanks doesn`t matter. I have a diesel so can`t answer your question about pumps. Good luck with it.

 

The fuel level sender(float) is bolted to the outside of the fuel pump resovoir inside the tank, it's pretty easy to change one you have the tank down.

 

LMAO 4 years later and I have still yet to correct this issue but i did run soem seafoam through the tanks. That seems to solve my fuel cross flow issue but not my gauge. So far i have lived with it. The werid part is when i filled the tank up the other day the gas gauge was on full when the truck is on and 3/4 when its off. Turn it back on and past full it goes. I guess I'll eventually get around to this but my other cars has been sucking up my funds for repairs and beings this is a backup car its been takign the backburner for a really long time.
