I've not had any issues with the high flow diesel pumps with my Allure until recently at a Flying J in SC (Latta exit, I-95). Even with careful modulation of the pump handle, I got tremendous back flow and fuel spilling. My next fill was at another high flow big truck island and I could run the nozzle wide open and no problem.

Was I just unlucky and picked a pump with a higher than normal fuel flow rate? I haven't used the J in a couple of years so have they upgraded their truck pumps to even higher flows? Will opening the fuel fill on the passenger side minimize this problem?

Opening up the opposite side could result in a major spill , you need to be able to see the only opening into the tank to prevent that.
From personal experience, even a slight slope of the coach side to side ; filler in use on the low side ; or high in the rear in particular can cause this problem.
Also my last fill at " J " I noticed that the fuel could be a % bio-diesel and I don't know if that contributes to the foaming of the fuel.

The high flow, large diameter nozzles seem better matched to the large opening direct into the tank designs of trucks. In Class A's they typically have a fill neck and connecting hose, sometimes a bend or two. I often have to 'throttle back' the nozzle by hand because even the first hold open notch is too fast. I have noticed that if the fuel island is tilted away from the pump (my fill side) I can fill a bit faster.

I have been at a fueling site where another motorhome had the opposite fuel cap off and was fueling from the opposite side.

This is something you do not want to do. It creates a huge fuel spill in a hurry.

I have noticed that some truck pumps have faster flow than others. It is something we have to live with when using a tuck pump. Just throttle the pump back.

You may need to check the vent tube, mine had some undercoating in it and was causing a similar problem, could be a dirt dobber too. Vent is located in front of tank on driver side ,if my memory is working. I have no problem with the power nozzles. Good luck

Marvin, I will check the tube. However, I've had no issue before or after this occurance with other pretty high flow commercial truck pumps. The fuel at this particular J was as lime green as I've ever seen so it may have had biodiesel in it. It really had a tendency to foam badly. The nozzle seemed to have only two speeds......wide open and stop

. I had a hard time modulating the trigger.
