Bruce,

My coach will give me problems filling from driver’s side but the passenger side fill tube works fine. I think it has to do with the angle of the filler tube (one being shorter and steeper than the other).

You problem may well be due to a vent being blocked.

Perhaps someone else on PC will chime in and explain the location and access to the vent line for our tanks.

Bruce,

I remember a few years back, Fast Roger had trouble on his XL II Country Coach with fuel “puking” as Jon calls it. He called Prevost and raised a little sand and they sold him a “kit” to fix the problem.

I don’t know if you are having the same problem he had, but he said that the kit from Prevost fixed the problem.

Maybe he will chime in or you can PM him (Fast Roger).

If both sides are giving you trouble Bruce, as others have pointed out, sounds like a vent problem. The 40 footers rarely have a fueling issue.
I lower the opposite side when fueling to get the tanks full, but that has nothing to do with your vent problem.

Hi Bruce,

I have the same problem with my H3. I always open the fill cap on the opposite side and still have trouble. The strange part about mine is if I let is get below 1/4 tank I have to hold the nozzle barely on. Once it gets to a certain level in the tank it will take the truck stop nozzle wide open??? I tried to fill at a Flying J RV tank once and it was just as bad. I would certainly like to find if there is a vent problem somewhere myself.

Hi Bruce and Linda,

I have not had any problems fueling mine from either side.

I have the problem at least partially solved. I had a good look at Chuck & Barbara’s H3-40. It’s one year newer than our coach, but the fuel fill system is quite different. Our coach has vent hoses that run from a fitting on the top of the tank (lower section) to the top side of the filler about 3″-4″ in from the cap. We also have a pair of reducer rings in each filler, one on either side of where the vent lines tie in. Chuck’s coach as neither of these “features”. The rings are small enough that I can not get the full size (truck) nozzle past the first ring. The restriction causes fuel to back up immediately and shut the pump off. We removed both rings from both sides. I filled up this morning on the passenger side, no problem. Without the rings in the way I can get the nozzle past the vent, and there’s no back pressure until the tank gets to full. As noted in a previous reply, the filler hose on the PS is shorter and runs at a steeper angle than the DS hose. On our coach, the PS vent line runs along next to the filler hose. On the DS, the filler hose is longer and runs almost flat. The DS vent line comes out of the tank fitting, goes above the filler hose, comes back down below the hose, and then runs up to the connection point near the cap. In other words, it forms a trap. I don’t know yet if that is a problem as I have not had a chance to try to fill from the DS.

Hey Bruce,

How hard was it to remove the rings? I have thought about that as well but did not know what I was getting in to.

Thanks,

I should have mentioned how we got them out. The constricter rings are press fit, but not that tightly, with three tabs to keep them lined up inside the fill tube. One of the guys I was “consulting” with on this problem had a somewhat heavy-duty “slide hammer.” Basically, it’s a long rod with a flatened hook on one end and a stop on the other. Inbetween, a metal cylinder that slides on the rod. Hook the ring and slide the cylinder back until it hits the stop, and work it loose. A word of caution; have some needle nose pliers and a telescoping magnetic pickup handy (we used both). We almost lost one of the rings down the fill tube and into the tank. Fortunately it hung up and our telescoping magnetic pickup was long enough to retrieve it. BTW: I have no idea what the purpose of these rings is/was, but when they went away so did my fueling problem, at least on the passenger side. Testing the DS will have to wait for the next fill up.

Thanks. I’ll have to look closer at those rings.
