BAD RUNNING
 

Thank you for your reply
The truck has only 44000 miles.
No fuel leaks etc.
There is no lift pump on the o/s/f on the block as it has a blank plate.
There is a small electric pump which has two wires in the C section of the chassis near the tank.
I do not know want a sock in the tank is, please can someone tell me

its pretty much the a filter on the end f the sending unit so it doesnt suck in crap.
