We have a National RV Tropical and when we put diesel in it splashes back on to the ground. It does not matter how slowly we add the fuel it still comes back, can anyone help? are we doing it wrong?

Most of the threads regarding this are old now. I have a 07 TropiCal and have the same problem, but not a bad as some. I have tried on several occasions to bring it up but the dealership really doesn't wants to discuss this. I have worked around it by slowly filling the tank. I can hear when it is starting to back up and I stop filling for a few seconds and start again. Some of the fuel stations use pumps that you can't adjust the flow of fuel, it is either fast or off. I had check with Freightliner but they tell me it is a factory problem as the tubes are put in at the time of build. They will do the fix but the cost is high. Great to see other ownere out here.

I had a slow fill problem on my FCCC chassis and they replaced the tank. However, they installed the vent tube wrong and I had backsplash. Once they fixed the vent, it was fine.

Does it backspash at both fill tubes? Or is it just the drivers side?

The fuel fill hose on my 99 Tradewinds was leaking so I purchased a new hose and replaced the line. The hose I installed was a little too long and created a trap going down to the tank. This caused the same problem your talking about. Shortining the hose fixed the problem. Look at the fill hose and insure is a continuous downward slope, any upward direction will cause this problem.

Haven't had a chance to check the tube. It isn't to bad and I am never in a hurry. It work fine most of the time. The back splash of the diesel is the foam and not the fuel. Jim
