fuel kicking back all over when filling

[MackDaddy]

My 2011 DSDP pikes back diesel fuel all over side of coach if I use big nozzle even when I have it filling slow as possible. Any ideas??

Keep a bottle of Purple Power (any spray cleaner) and an empty Big Gulp cup handy. After the inevitable fuel splash - finish filling, put the fuel cap on, squirt the Purple Power all down the side and rinse with the Big Gulp cup filled from the windshield washer pail.

Works every time!

FWIW - I'll estimate how many gallons I need and back the pump off to the slowest setting for the last 10 gals or so. Seems to eliminate (or minimize) the splash more than half the time. I'll also use the RV pumps at FlyJ as they run the smaller nozzle.

Try turning the fuel pump nozzle sideways when adding fuel. I find that if I turn the nozzle 90 degrees sideways, instead of straight in, I can fill my tank faster. Then I start listening for the gurgling sound that tells me it's nearing full and I slow down the fill rate. It kind of depends on which way the fuel fill hose runs to the fuel tank.

If you have fillers on both sides of coach, open both (for a vent) when filling.

Of course if you arent level, the fuel will make a bigger mess on the other side.

Ditto on this.

Mine used to spit up as well. I take both caps off when filling now and have not had a problem since.

Thanks for comments have done the usual but have not tried opening other fill cap for venting will try sounds like good idea

have same problem..both factory and Spartan looked at, nothing found and have tried every combination of flow/nozzle/ and caps on and off. No help, now try and guess how many gallons and stop before and stuff paper towels around nozzle...best of luck...my guess is bad placement of vent and not sized correctly..
