Same here. Mark, take off one clamp, 3 screws and pull the pipe. Cut/clean, and reinstall with the adapter tee.

I've had a 37 gallon gravity feed tank for about 8 years and installed it in two different trucks. I love it. Makes things much less stressful for me.
Think it was around $500 with the gravity fill kit from Northern Tool.

Both trucks were/are short beds with 26 gallon tanks. Looking for a fuel station every 200 miles gets old quick.

If I could not buy another, I wouldn't sell it for $2000.00

Will a gravity feed tank work if you have no fuel cap like we have on the RAM? How does it keep from overflowing?

I did the same and this is the 2nd truck I did that too and the new truck is a long bed so I ended up with 62 gallons, I didn't want to give up space in my truck bed.

You have to cut the filler neck hose and install a T fitting in the hose.
This T fitting has a float ball valve that close off when the fuel gets up to it.
I've had ours in two different trucks over 8 or 9 years and it has worked perfectly every single time. (Chevy and Ford)

You simply purchase the T fitting kit that fits your truck. (The filler neck hose is different diameters on different trucks). The kit comes with everything you need to install the gravity fill.

I'm not familiar with the fuel cap on your Ram.

Funny Story. Have a friend with a Ford 350 diesel. He put his aux diesel tank in the bed and enabled the gravity, drip feed. after driving a couple of days, he got an engine light. Turns out the onboard computer decided something was wrong because he had driven 700 miles and his fuel never dropped below FULL.

Which tank did you get? How much room does it need from the back of the bed to lift the toolbox cover?



Thanx Dean

Dean, it's an RDS-72775
I have a Roll-n-Lock cover, but the tank is up flush to it.

My Ram tank is 4 gallons less than the Duramax was, so I don't think I can get to my normal stops now without getting fuel.

I'm trying to decide between the 40 gallon rds tank toolbox combo transfer, the rds tank toolbox combo with pump and nozzle, or just going to truck stops and paying another 30 cents per gallon.

I don't like the idea of cutting into my filler neck for the transfer combo, scared of getting metal shavings in my tank. Does cutting into the filler neck cause a possibility of warranty issues?

The rds tank/toolbox with pump and nozzle costs about $500 more.

The plus of having extra fuel would be I could stay hooked up for our quick overnight stops and get going in the morning quicker, plus the savings on fuel costs. It's going to take a lot of fuel though to overcome the transfer tank price (800) or the pump nozzle price (1300).


I can't make up my mind.
A few years ago when we went full time with our F350/Montana I knew I had to increase my fuel capacity. Looked at all the possibilities since I had a really small tank.

Even being full time we planned on spending 4 winter months stationary in SW Florida, 3 months stationary up north, and then just 5 months actually traveling all over. So in reality I would only need the extra capacity for the 5 months of traveling.

I purchased four 5-gallons diesel cans with ez-pour nozzles. They fit perfectly in a low bed tool box I had and the cost was cheap of course. It took a little more work to add the extra 20 gallons when I needed it but being retired I had all the time in the world.

When we came off the road and bought another house I sold those cans for about half of what I bought them for. I would guess 2 years of having extra capacity fuel on board cost me in the neighborhood of $25 to $30.

Sorry, I do not have the combo tank/toolbox, but I do have an ATI 51G tank that I absolutely love. Since I already had a low profile toolbox, I put the one that barely sticks above the rails but is only 8" wide. I love having extra fuel.

On my setup, I didn’t cut into the large filler hose, instead, I plumbed into the 5/8” tank relief vent hose. Since I use a fuel pump instead of gravity feed, I tapped into the relief vent up close to the fuel cap. Works great.
