Fuel Probelm

for some reason I have these two problems with my truck!

When I am on the front tank gas gauge bounces around like a HDD Kid with lots of sugar, I know when I am low on gas on that thank when it goes to F and stays there.

Problem number 2.

My gas keeps going from front to rear at all times making it nearly impossible for me to get an accurate reading on my mpg any help I'd appreciate it!

Is the needle constantly moving, or just when your on the gas?

The TSB involves installing a one way valve on the return line. Haven't done it to my truck, but doesn't seem to be a major job.

You have 2 problems. The fuel level thing is a bad float or possibly a gauge if it happens the same on both tanks. Fuel transfer between tanks is due to broken check valves in the fuel sending unit inside the tank.
