Canadian Hummer Club Forums

I noticed every one in a while when I switch tanks it takes a bit to "switch " like up to 4-5 minutes.

Sometime fast,.. Once in a blue moon it won't but hen I turn off the truck and back on it goes to the proper tank,

I'm ok with that for now, but on Saturday I filled both tanks and drove home, and noticed on Sunday when I got in, it read 3/4 full? "With 5 minutes of drive home time from gas station"

I then switched to aux tank and needle didn't move?

ill see how she goes today, but anything to look at? Lol I tapped fuel tank selector valve, not sure why, "figured a tap tap fixes all" but nothing happened , hehe

Plus I seen some drippy tranny return hoses I gotta address

Ps, after going threw a few forums, (I did way over fill) it started JUST started after I filled..

Lol, I even remembered after the gas clicked I kept trying to squeezing in as much as possible per tank ..I mean squeeeeze....

I'm hoping after a week might go back to normal, I get a feeling gas went into the vent lines,
