Has anyone made the switch from the smaller diesel pump nozzle opening to the larger size to accommodate the bigger pump nozzles I keep encountering? Lot of time to stand there and hold the heavier nozzle so the fuel doesn't spray back, or am I missing a vent tube that allows air to escape while filling with the larger nozzle? If I insert the larger nozzle all the way in it really spits back out the fill tube.
If you changed over, where did you get the parts and what did you have to modify to make it work?
I never had any of those issues with my 1990. Maybe you are right to think there is a vent plugged???
Norm, I have the same problem in the 1997 U295. The problem is especially bad with the nozzles that have a big rim at the end to help that stay in the truck tanks. I've considered opening the cap on the opposite side, but never tried it. If the nozzle keep spitting or kicking off, I just hold it further out and run a slower rate.
There is no vent I am aware of on the ored. Small tube back to the filler neck is what I remember.
My personal long term tested method of filling the tank in oreds was to dump the coaches air with the jacks down but not leveled. At that point I manually extended the front jacks until the front tires were in the air.
Down hill to the tank allowed more fuel versus any other way. Faster? Have no solution for that one. Less spit back with the front elevated. Lots of funny looks in the fuel stations.
Retract the front jacks and start the coach bringing up the air then flip up the levelers.
Otherwise tank was always missing 10-15 gallons of fuel.
You can feel the fuel sloshing front to back in an ored partially filled fuel tank after coming to a stop for a few seconds.
Not enough dampeners in the tank.

JD, I have the same problem you do and compensate just exactly the way you described.
Bob, I don't have any "air" to dump. Our coach is the old Oshkosh Truck chassis with leaf springs and no "air". But, thanks anyway for the info re not having a vent tube. This explains why the fill hose going from the nozzle opening leaked once when we had a really full tank of fuel and when it expanded the fuel pushed by the hose clamp near the top.
You can still elevate the front with a spring chassis. I used to pull into gas stations and make sure I was uphill if possible...
Make sure the coach will not move and fall off the jacks.
