Took 30 minutes, two cups of coffee, and one donut to install. Hooked up to a 40 gallon tank, works great.

Great Product-Some Difficulty Installing...

2012-Dodge Laramie 3500 Ram Truck. Became instantly apparent the outer molding & inner wheel well housing had to be removed to access the steel fuel line inlet tube on main tank, (I do have the 1.5 inch fuel fill line). Removed factory hose clamps, where the rubber hose connects to the fuel neck coming off the main fuel tank. Then, literately, had to cut the factory rubber hose off to remove it. It is a tight fit. Note. If at all possible, try to save the factory hose as it can be reused in place of the two 1.5 rubber hoses that are sent in the kit. This hose has a factory bend molded into it. You will need a straight chunk of hose to fit from the metal 1.5 pipe to the fuel tank.. short as possible. You want the 1.5 pipe touching the plastic neck of the tank inlet. the outer hose (the hose that goes between the kit pipe and the fill neck has to have almost a 30-40 degree bend to make that connection. It is a very tight fit. That's why I say use the factory hose if possible. Kit comes with two 1.5 clamps. You will need 4 total to make these connections. After mounting the diesel tank, drill a 3/4 hole in the side of the truck bed, directly off and adjacent to the petcock of your auxiliary tank. I used a key-hole saw bit. Makes a clean smooth cut. Then remove any metal burs that might have remained from cutting hole. Connect 1/4 ID hose, clamp both ends. One clamp on each end is sufficient. Reinstall wheel well/molding. Make sure fill caps on both tanks are tightened until they ratchet or click several times. Open petcock on auxiliary tank. You're good to go. Took me a good hour. My recommendation... If Camping World does the job for an installation fee, I'd just get them to do it, depending on whether you have mechanical experience or not. In conclusion... Great kit for the price. Good Sam Members get a discount which really helps. Enjoyed the installation, but did scrape a couple knuckles, but what fun would it be if you didn't. Good Luck! Camp on!
