I agree with ibnfshn...mine will will I top it all the way off..I have two 12's in my Ranger. You may simple want to add some line to it if you are having this problem...this was a TSB on Johnnyrudes...well not the exact thing...lol. On the pee hole hose, you need to route the hose up over the cylinder head...this keeps air from entering the system and causing hot spots in the head. Same thing here...maybe try to add some line to it and put a bend towards the top or something to get it further from the tank and have an upward angle to make it more difficult to run out. Just some thoughts...thats an odd deal though.
"But if serving the Lord seems undesirable to you, then choose for yourselves this day whom you will serve, whether the gods your ancestors served beyond the Euphrates, or the gods of the Amorites, in whose land you are living. But as for me and my household, we will serve the Lord.” Joshua 25:15
