We have 02 Marquis Tourmaline non tag. I was wondering if there is a trick to fueling without spilling diesel. No matter how slow I fuel I get alot of blow back. Thank you for replies in advance.

Try fueling with a auto diesel fuel nozzle instead of the high speed truck nozzle. They fuel at a slower speed. Also, try fueling from one side or the other. I find that filling my Thunder from the right side using the auto nozzle I get no or very little splash back.

On my '04 Monterey, I had to put the nozzle in only enough to put the lip of the nozzle inside the filler opening. Then usually I could fuel with the nozzle set to the lowest notch. One of my favorite fuel stops flowed too fast, even at the lowest notch. I made a wedge for the handle out of thin plywood that would hold the nozzle open at less than the first notch.
On edit, I see that while I was typing Marty beat me! Good morning Marty!!

I will give it a go, thanks

Roy,
The fueling problem on your SMC era Beaver is caused by the tank location in most cases, because the tank is located above the front axle in the center of the coach with two or three 90 degree bends in the filler hose between the filler neck and tank. This fuel tank arrangement mandates a slow fuel flow rate when filling, so using a high volume truck nozzle at full flow is impossible.
If the tips in the post above do not correct you issues, you probably have a restricted vent valve. The vent valve is located at the end of a 3/8 inch hose that is located at top edge of your fuel tank, usually the LF edge. The vent valve is a check valve that lets air escape from the top of the tank as you add fuel. It is fairly easily cleaned or replaced if necessary, but do not remove it because it is necessary to prevent fuel leaks.

On our 06 Monterey, we found that removing the cap from the opposite side allowed better venting & a fast fill..........

Thanks all, I will check on these Ideas. Appreciate the replies!

If I try to fill my Monterey from the passenger side it will not allow either the auto nozzle or the diesel nozzle to flow more than the first notch. I ended up milking over 40 gals. in after the nozzle tripped off.

Dennis,
Removing the opposite side fuel cap will help on many Monaco built Beavers, but you need to be careful to be level so you are not pumping fuel out the other side. However on the SMC built Beavers like the one Roy was asking about, it will not help because the filler hose enters the tank at about the 1/4 tank level and the only way for air to exit the top 3/4 of the tank is the vent hose.

Thank you Gerald.

I sometimes have issues with filling the tank on my 2001 Contessa too. I always use the truck pumps with the bigger nozzles though. I usually end up having to hold the handle the whole time but every once in a while I get lucky. My gas cap fits behind the handle and locks the trigger on the low setting every now and then and saves me from holding it forever.
