03 F250 Fuel Gauge
 

Howdy, I have a 03 F250 V10. I just put a 30 gal tank in with everything new, now my gauge won't work? At first it did for about a minute! SO i took out the tank and checked everything with ohm meter "good" and again about a minute later it kick off and won't work? Anyone got ant ideas?

If it worked fine before changing the tank, something in the process either disturbed a connection or created a problem for the signal to get to the dash unit.
