Fuel fill
I just purchased a 2002 Vantare and when I fuel it the fuel gushes out of the fill tube when it get full. I have tried slowing down the nozel, also tried using am smaller car tyupe nozel, also tried takining the fuel cap of on the other side. None of these seem to work it still gushes out about a half gallon of fuel when the nozel shuts off. I also have a raw diesel smell inside the coach at times not sure if these two thing are connected in any way.

Prevost has an upgrade to the filler neck. I would suggest you talk to Prevost about the issue and they might have the kit for an H. I know it is available for the XL.
The issue has been solved for the XLII, at least my vintage. Prior to my 06 XLII I had a 97 XL and like you said it would puke copious amounts of fuel. Cost me a new pair of jeans and a pair of good shoes.

I feel your pain, mine does the same thing. You didn’t say if it was an H or XLII, mine is an XLII. I thought they fixed it with the XLII, but maybe in later models like Jon’s.

If you have an XLII the problem is caused by the fuel fill inlet in the tank being below the top of the tank. When fuel enters the tank, when near full, fuel goes above the fill inlet in the tank. The fuel above the fill inlet is then forced down and out the fuel fill neck. There is a fix, but only for one side (passenger’s side I think). The fix is effectively a ball in the fill hose that blocks the hose when fuel pushes out of the tank.
What many of us have done is learn to stop filling at about 20 gallons from full. Then we either stop or try pumping very slowly and just a bit at a time. Typically, the fuel burb doesn’t happen when using the slow car pumps.

I had that problem. I just tilt the coach to the curb-side before filling. Since I started that practice, no fuel burping.

Some of my personal rules;
Fill in the AM when it is cooler and you are rested (more patient).
Fuel added at the end of a hot day to an empty coach will expand and possibly cause fuel vapor odors in the coach when stopping for the evening. This is another reason for not going below 50% before fueling. Remember fuell in underground tanks is cooler than the fuel in the coach tanks.
Do not fill at the end of the day when you are fatigued hungry and impatient.
Set the nozzle to the lowest setting. When it first clicks off, stop and add no more fuel. The small amount you might add will mean nothing in the grand scheme of things, other than probably cause you grief and to smell diesel in the coach due to overfilling.
If your in a hurry remember, stopping short of a spill takes much less time than cleaning up the resultant mess.
Never fuel up with the over the road air conditioning running. You will suck diesel fuemes into the coach.
Get to know your fuel gauge, that is when at 50% add XXX gal and be done. You will learn how many.
Plan ahead and look up where your next fuel stop will be.
Run off the top of your tank, you will have a great feeling of well being.

My 1991 H340 will whistle when it starts to get full warning to slow down. The higher the pitch of the whistle the closer to full.

Single side fill and late model XLII fill pretty much trouble free. Dual fill on XL without the fix pukes.
Amazing folks would not jam as much fuel in the tank as possible as a solution. I dislike truck stops and will do almost anything to minimize the number of fuel stops.
This problem is a black eye for the “Ultimate Class”.

Seems there are several reasons for that black eye.

Just reading what Larry said makes me think about how a company could make a commercial vechicle that you can’t put fuel into with getting soaked or creating a hazardous spill?
-
I know for sure you could run the fuel from a truck island nozzle at full flow into the single side fill on the early XL coaches and not spill a drop. And then you could nurse it to maximize the fill. Still no puking.
But the two side fill coaches prior to some XLII models not only shot copious amounts of fuel out the filler, it was blowing the fuel out a few seconds after the nozzle shut off. That pause was what got me soaked. After that I just stood to the side and let it erupt. When it was all done I would pull the nozzle, cap the tank and drive away. I usually walked on the island so I did not have to get #2 on my shoes.

I’m surprised the EPA hasn’t put pressure on the DOT to have a recall issued. The first time this happened to me my fuel fill was right next to the pump. What a mess it made of me, the coach, and the pump. I never pull up immediately adjacent to the pumps anymore and have done pretty good at controlling the unexpected discharge. It’s a good thing they don’t make boats. Any spill in the water will get you a $10K fine and possibly the cost of cleanup.
It’s not a boat and there’s not an easy fix, so most of us just learn to live with it.
