    • Small kit but effective.
Installed easily, had to shorten just a little the intake pipe on just one end to allow the provided thick rubber hose to slide in! Use lithium grease on rubber and easily slide into the pipe. Working great.

    • really a great product
Don't kink the hose and mount the tube as close to flat as you can with the float valve straight up. check hose clamps after the first couple of tanks of fuel.

    • Absolutely wonderful fits my 2019 Chevrolet 3500 dually Duramax
What can I say Great package to the job, the only thing I would recommend Is that the hose to be a more UV friendly hose and/or have a specific section that is covered so that way the UV light does not crack it. Had my installed for a couple months now it does its job absolutely wonderful, I did change out my ball valve though so that way I can get a 90° angle with a bigger handle, but the rest of it still does its job perfectly, I do just recommend that they make the hose more compliant with being able to get even by the sun, as I did have to throw a rag on top of the section that is exposed to daylight in order to prevent the sun from cracking it, as a piece of tubing that I left out in the sun before I installed it did show signs of sun crack, so I do recommend that you find a way to put a covering over it or just a rag or something to assist it there so that way it does not get eaten by the sun ... show more

    • Easy install. I had to remove the check valve
Fit well. Easy install. I had to remove the check valve, as it was restricting flow and tended to stick in the closed position, otherwise, works as intended.

    • Works great. Installed in a 2017 Nissan Titan XD Cummins.
Review Image by It's me It's me
Combined with a 50 gallon RDS auxiliary diesel tank, it has greatly extended our range when towing our camper, literally no more worries about making it to the next fuel stop in the middle of nowhere. I can't speak to the install process, I paid a local diesel shop to do the work, but they didn't complain and came in right on the low end of their install quote, so I don't think they ran into any problems. ... show more

    • Works in my 2019 Ford F250
I installed in my 2019 F250. I wanted to install an RDS auxiliary/transfer tank. Fit and made the installation extremely easy.

    • This is JUNK!
This product is terrible had to pay mechanic twice to install. First one leaked from time it was installed. Company wouldn’t respond to my email about the problem. Had to buy the whole new kit just to get the value part. Had to pay again to have it installed. Works worse than the first one. Pours fuel all over in truck. Don’t buy this junk! I would give it a negative stars if they had them. ... show more

    • Good value
Easy to install, very simple design. We installed an electric valve that closes when the truck is off but I really don’t think the system needed it!
