Problem filling the tank!
Has anyone had a problem filling their motorhome at the gas pump? Can not seem to figure out why it is taking forever to fill up with the nozzle shutting off at the pump due to the constant backing up...

It sits in line with the fuel tank vent and captures fuel vapor, which is then drawn out again during engine operation. They've been on vehicles since the late 60s or early 70s, and are there to stop gasoline vapor from venting to the atmosphere.
Thanks for all the suggestions. I just heard back from the seller saying he took the unit to another garage and they supposedly diagnosed the problem due to something called the canister. I wish I was more up to speed on such, but I really have no idea what the canister does or why it 's demise would effect the filling of the tank???

If a system is overfilled with fuel (or has any of a select few other problems), liquid gasoline can get into the canister and turn the charcoal pellets into something resembling black concrete. Once that happens, the tank won't vent air properly as fuel is added.
Does that help?
