Gee and I thought I had problems today! At least I can drive my coach
and use the gas tanks.
I don't know the cause of your problem. I just know that when I fill up
my coach I have to go very slow after about 15 gals (if it was close to
empty) at about the 1st notch. If I don't do that, I'll get fuel coming
out of the filler. It comes out in quite a gush! I supsect that if I
left
it running at the 2nd notch like you did I'd get a large puddle under
the coach.
The first time it happened to me, I was really suprised at how much gas
shot
out.
The problem is apparently caused (as you probably already know) by the
return
line (for the air being displaced)is too small and probably has kinks in
it.
My tanks gurgle for quite some time after a fill up. Maybe for as long
as you
report, but I don't keep track because I'm usually driving from the gas
station.
This has to be discouraging. You've been working on the lady for over 2
years,
getting close to being able to finally drive it and you have a problem
that has
you spooked.
I don't know if this helps, but at least you have company today with
someone
who has had problems with his GMC as well.
