I have a 97 TJ that has one of those gauges that likes pissing your off.
Well it doesn't fill all of the way and I think I found out why. I was
reading into my rig and came across a noted problem it said "The gas tank
may fill slowly or the pump nozzle will keep shutting off due to a problem
with the fuel-tank venting system. (1997)" this is a direct diagnosis of my
problem.

My question is does anyone know anything about this or how to fix it? I am
so sick of the gauge being messed up and my 19 gallon tank only holds 15
because the damn thing won't let me fill it all of the way. I know it's a 19
gallon because I checked the part # plus when the pump shuts off the gauge
will only read just over 3/4 full. Can't get it all the way full

Have you tried filling it the rest of the way from a portable gas can just
to ensure that it is really possible to put more gas in it and you aren't
just not using the last 4 gallons in the tank? Another test might be to run
it all the way to empty -- true empty, not just when the gauge hits 'E' --
and then fill it up from a gas pump... If you can still only put 15 gallons
in it, I would then try filling it the rest of the way by pouring gas from a
5g can into it until it overflowed... To ensure that you don't run into yet
another venting problem, perhaps a hose running all the way into tank would
work... That should allow it to vent around the sides of the hose and you
should be able to fill it up to the point of it overflowing... There is
still probably an expansion area in the tank that you might not be able to
easily fill...

Its quite common to collapse a fuel tank when the vent valve on the fill
cap is blocked, then it doesnt take much vacuum from the fuel pump to
collapse a tank. Too bad such tanks arent baffled . .. the baffles would
hold the tank from collapsing.

86XJ Cherokee .... used to have 15 gallon tank .... now "crushed down"
to 11 gallons capacity.

Has anyone actually done this? If so, what year Wranglers?
