Have 120 gallon auxiliary fuel tanks on several of our Duramax diesel rigs.
Having a fuel feed problem on one of our 2004 C4500 Kodiaks. Dealer in Colorado disconnected the aux. tank claiming the 3/8" feed lines are too small and all plumbing has to be 1/2". Now we're on the 25 gallon stock tank, which means we have to hit every other gas station. Personally, I think dealer is full of BS as don't have any problems with our other similarly equipped rigs.
Haven't had a chance to run it only on the 25 gallon tank and see if cured our problem as had a tow truck yank our truck from that dealership and take to another. Friggin' idiots wanted to argue with my driver that he should have used his engine block heater overnight as engine started then died and w/n start again, the morning after they "worked" on it. This truck has NO engine block heater setup. It's a Texas truck.
When new dealer received it, they ascertained that the first dealership had run the 25 gallon tank dry and hadn't switched the fuel tank selector switch from our, now disconnected, aux. tank, so the guage was reading full.
I checked with several 4X4 and custom type shops who agree with me. They use 3/8" with no customer complaints. One advised they equipped 4 Kodiaks a few weeks ago - all with 3/8" and numerous 3500's over the years and no problems.
Anybody experienced any similar problems? Are 3/8" feed lines adequate or inadequate?
