Checking the DEF level

Hello Thor Owners!

I have a 2016 Thor Four Winds 33SW Super C motorhome on the Ford F-550 chassis. I have not been able to locate the DEF level indication system, if there is one. I have also been very frustrated when trying to fill the DEF tank at the truck stops.

Any help would be greatly appreciated.

Thank you,

Marshall Poe

Ours only displays a message when the level is low, no ongoing display that I know of on our Mercedes Sprinter chassis. Don't know if Ford does or not. We were advised to refill DEF every 7th tank of fuel. I was also told that once that DEF warning message comes on, you can continue to drive for quite a few more miles, before it runs out.

Well, the DEF tank fill issue was solved by ordering the 21GU Mis-Filling Prevention Device (MFPD) (see picture). It contains the magnets necessary to allow you to fill the DEF tank at the DEF pump at any truck stop.

I have the same issue on my Class C chateau. It will not fill properly and shuts the pump off every two seconds. Takes me forever to fill it. Is this the problem on a gas engine? Dealer told me pipe was crushed and they fixed it but said it was a Chevy problem and not a Thor problem

It may be. This device tells the pump to lower the fill rate for non-semi truck tanks. I know this fixes the DEF fill issue.

Does this part just snap in over the existing gas Inlet?

No, this has nothing to do with filling a gas tank. This device is for the Diesel Exhaust Fluid (DEF) tank fill.

Comments/questions about filling a gas tank are in a different thread.
