I'm looking at 2 trucks and both owners have or are having an issue with fuel gauge malfunction. Both have blamed a Fuel Sender/sensor on the culprit. Is this a big deal repair. Some time the gauge I'm told doesn't read when full or near empty. My 05 never had an issue. Was I just lucky. How problematic is this. Does low miles say below 40,000 cause this to not likely occur.
