Re: 6.0 runs and quits

although it looks that way the return doesn't go straight thru the filter/reg....
id check the tank switch valve and make sure its letting fuel go back to the tank

correct...the outside [3/8] is from the fuel pump ...the center [5/16] is the bypass return
you could have a bad reg or its deadheaded at the selcto valve
