Need some help/fuel problems

[Stillrunning]

I dont have a loop in mine and it seem to be ok. It might be the opposite and moving the loop down lower would solve the problem. My thinking is that gas is in this loop. When you stop the gas (in the tank) shifts foward forcing air up the hose and this is pushing the gas in the loop out the vent. If it was lower the gas in the loop would have futher to travel and not blowing it out the vent.

When you fill up do you keep toping off after the pump clicks off?? When you fill just listen you will hear he air blowing out and no when to stot, but as soon as it clicks off don't try to round off the pump, You are FULL!

What Wind Talker said

You've got to be real attentive. I smell gas fumes if I take it too far so first I estimate how much fuel I need to fill up. Then when I start getting close to that I get real close to the vent and listen listen listen. You'll hear the air and or gurgle just like MJ said. Stop right there! Hope this helps.

Thanks for the help. I have raised the loops and now I only put about 12 gal in each tank and so far no spray-out.

Fill it up and see next time. The setup you got should be a little better than the on I have. Mine is straight from the tank to the same location you have with 2-90° fittings between the two.
If it does spew while trailering just say "I'm returning back to nature" and keep driving.
