RDS MFG INC 11025 Diesel Install Kit

Works great on my 04 ram 2500. Has been installed for about 5k miles with zero issues

Easy to install

Great idea and design! Now, it took me longer to install this than I thought it would, but is a cool design. It comes with all the parts needed to do the install, and although the drain fittings are small, making it slow to transfer the fuel if you just use the tank as a holding tank, the system does work seamlessly. I have two suggestions for improvement. One is that the tee that the fuel feeds in through is tall enough that it creates a clearance issue with the truck bed when mounted. If it can be designed so it was shorter height from the cross-pipe it would help it mount without hitting the truck bed. The second suggestion is including a rubber grommet with the kit to protect the rubber hose where it passes through the truck bed. Time will tell about how the system works but so far it's great.

Works as intended. I bought it 9 months ago just now got around to installing it. The filler neck on my 1985 gas truck is 2" and the T fitting in the kit is 1.5" so I had to get creative in a pinch and make one out of PVC. It works great.

Bought this for my RDS Fuel Tank Tool Combo - 60 Gallon, Model# 72743 to install in my 2016 Ford F350. I have the truck to pull my 41' fifth wheel. When hauling the 16k pound trailer, the gas mileage drops to about 8 or 9 mpg, hence the auxiliary tank install. Enough about the reasoning, lets get to the kit. It was easy to install, plain and simple. The tank took a lot more time of jockeying back and forth to find hole locations to drill. The kit was quick and easy. My Ford has a metal fuel line from the fill cap, transitioning to rubber after about a foot. I was able to cut back the rubber line and install the kit at the transition from metal to rubber. I did have to cut about 4-5" of rubber hose back and use one of the couplers provided (see photos). The parts fit together perfectly and wasn't difficult to line everything up. Be absolutely sure to install the kit with the fill valve as perfectly vertical as possible. If it is not vertical, the check valve will not work correctly and you will lose fuel, as much as 60 gallons if you don't notice the issue. I also recommend using a larger hole saw for the fuel line from the tank to the truck's fuel line. My layout had the valve stem from the tank almost touching the angled truck bed, I had to enlarge the hole for the fuel line to pass through and give room for movement. I used the leftover fuel line to add a piece to the breather valve on the tank and placed it facing up, less chance of splashing diesel in the toolbox.

Perfect fit for my truck

I installed on a short bed 2004 F-250. There isn't much room under the bed for this unit. Cutting the filler neck hose was the hardest part. It finally occurred to me to use an oscillating cutting tool. I could not do it with a sheet rock knife or hack saw blade. Once I got the hose cut, the kit went in just fine. I made sure I installed the T in a vertical position and used a grommet to protect the hose going through the bed. I have run 4 tanks of diesel though the valve without any issues. I use an RDS 60 gallon tank which is a wonderful solution for a truck with a stock 29 gallon fuel tank pulling a trailer.

Good quality and worked well. Just used on a 950 mile trip. The aux tank gravity feed flowed into the main tank as I was driving. Turned on aux tank when main tank was about a 1/4 full and it filled as I was driving. Fuel range increased slowly. Very pleased!! Used on a 2022 Chevrolet 2500HD Duramax.
