Dropping gast tank to check vent line

I had a 1 ton drw Chevy that I had a service body installed. The first few tanks of fuel were hard the put in. I brought it back to the service body installer. They found the rubber filler hose kinked. Just a thought. Good luck, hope it's an easy fix

Still Having that problem??

Let us know what you find out....

It was a problem with some mid 2000's Fords. The hose could kink

Had the rv looked at by my mechanic. What he found was that the fuel line did have a sharp turn in it that could possibly be a kink. Also the rubber hose line was cracked. Not all the way through but was going to be an issue soon. He did not have to drop the tank as he was able to get to the line. He did say that he found some gas in the vent line and that the fuel line itself got thinner as it got to the tank. He blew out the line and did remove some gunk. He thinks the biggest issue was that the hose had a few dips in it which would cause it to back up. When he replaced the hose he tried his best to keep it level or angled toward the tank. I won't know the result till I fill in another state. In CT we have vapor nozzles which I from what I am told restrict air flow. Here's hopping.

Your mechanic experienced pretty much what I did working on the Jayco. The lines were drooping, they were deteriorated, and it was BARELY possible to reach the tank without dropping. And yes, it fills more easily than it used to. I try to park nose-down at the pumps if I can, but level works. I doubt if I could fill it nose-up.

I had a smog issue due to a leak in the top vent line. I absolutely did not want to deal with dropping that tank at home. I gladly paid to have that done.
