I have a 08 f 350 im running a 40 gallon transfer tank in the box hooked to a small pump. works good till i hook it to my gooseneck trailer then it gells up when it is around 10-20 above 0. there is not enough anti gell or #1 to keep it from gelling!!!! Wonderd if anyone else has this problem or if it is fromthe short hose that runs from the pump to filler neck. thanks for any sugestions. william
