I did indeed crawl under the rig to check the fill hose and as cbach and gmthrust noted, the hose is routed so that there's a dip in the middle.

I had the same problem with the rear diesel hose, so I guess I should have guessed earlier. Problem with the diesel was just a quick shutoff and not the explosive regurgitation.

I'll re-route the hose and retry filling. Thanks for the tip about the fill hose, I'm dropping it off at the Ford dealer tomorrow for service so I'll grab a hose there.

We just returned from a round trip for SLC, Utah to Charleston, SC. 5000 plus miles, so I was nearing the point where I finally *needed* to fill the DEF.
