Did you replace the front fuel pump (FDM)?

If the gauge is always on empty more than likely the floats have sunk.

Can the selector switch cause the front tank not to work?

Just in case it is not the switch, what else could it be?

Ok. I have replaced the front fuel pump and sending unit. I have replaced the fuel selector switch. What else could cause the problem. I took truck on test run, and it did fine except when going up hill. It started to sputter and starve for fuel. It is really starting to tick me off. I do not know what else to replace to fix this problem. If anyone has any ideas please let me know. Thanks. Happy New Year to everyone.

Neither tanks are getting fuel now

I have the same issue and now both the front and back tank isn't working. Did you ever find out the cause? I replaced the fuel pump and fuel relay switch.

Thanks!
