Bizarre fueling situation. Issue #1 on trip.

2009 Cambria. Half a tank of fuel so let's fill the tank before heading to Bishop and some trout fishing. First station, arco, the pump keeps tripping

and gas won't flow. Tried pushing the nozzle into the fuel filler, all I got was a gallon. Pull ahead to next pump, same. OK, head down the road, pull

into a Shell. Insert CC and bingo, pump will not activate and flow fuel, pull ahead to another pump, same ;tried the 3rd pump, same. So I called my

friend brother James. Now James is a Class A mechanic. James worked for FORD Motor Company as a "lemon fixer" When the dealers

mechanics were stumped James arrived. He said it sounded like either the vent was clogged OR some have a solenoid that shuts the fuel opening

in case of vehicle rollover. He's talking cars, not motorhomes. Suggestion: fill it using a fuel can, see what happens.So, on my way to Adelonto and

a store for a can. On the way I got to thinking. Dirty vent? Stuck valve? Maybe a sloshing of fuel will clean it out. I pulled into a Chevron and went

to the furthest pump away from anyone and did a hard stop, (maybe 5 mph safely) put it into reverse and did the same. Well guess what, it took fuel and many stops

after that. I need to study and learn how RV fuel tanks are set up to determine the cause.

PS> One thing I did notice when removing the fuel cap was a lot of vacuum in the system, a whooshing sound when removing it.

Ohh yeah, after fueling I went to stock up on food, my CC was locked for possible fraud use. Too many attempts at too many locations.

  • Sometimes the fuel filler pipe has to be longer and more convoluted to reach from where the chassis manufacturer places the tank, to where the coach manufacturer places the access door to the fill pipe. That's assuming the upfitter doesn't move it, to add some piece of equipment. My 2002 Roadtrek was like that. They moved the tank forward to make room for the Onan genset, and had to run a longer fill pipe with an odd bend in it to reach the access door. It was always hard to fill the tank without rotating the nozzle 90 degrees to the right, to get around the oddball bend in the pipe.
    Maybe?
    Interesting that sloshing the fuel fixed the problem. Probably not the same issue as my Roadtrek, if that did the trick.
