Any issues? My understanding is you put it in, plumb it and only fill the aux tank right?I thought it was straight forward till I read some reviews on Northern Tool for the connector kit. There were a few talking about fuel seeping out around the neck over flow etc. Some said that the ball valve in the connector kit stuck and caused leaks. Anything to this?I assumed you hooked it up and only used the valve if you had to open your fuel cap for some reason.Please enlighten me. I have a trip planned the week after Labor Day and I am thinking about putting one in.

I put in a RDS and gravity feed kit. When you need fuel just open the valve.Here is a write up of my install. Start at post #52

My wife bought me the 35 gallon tank and pump for Christmas a few years ago. It's a bit more of a hassle to manually pump the fuel, but not that big of a deal. It has an inline filter so that's a plus. Usually when it's time to transfer fuel I'm ready to get out and stretch my legs anyway, so that's a plus too. I wouldn't own a tow vehicle without an external tank, just too many good points, and no bad points.

Auxillary fuel tank-IMHO, Unless you know 100% how to install the auxiliary fuel tank, have the tank installed by a shop. Gas leaking out of tank is too high of risk for my safety. A $1.00 saved could be very costly down the road!

Have the 38 gallon in bed tank with gravity feed. I put a solenoid on the tank line and turn it on when truck fuel tank reads 3/4. No problems and no leaks.

I bought an RDS 45 gallon in bed tank about 6 years ago, originally put it in my '06 RAM. In February of 2015 we bought a '15 RAM, I transferred it into my '15 soon after. I have NEVER had any issues with my set up in either truck.

When the truck tank gets low I switch the auxiliary tank valve and refill the truck tank, easy as that. It will take a couple of hours for the fuel to flow into the truck tank. LOVE the extra fuel capacity!

I used a RDS 50 gallon combo tool box on two different diesel trucks. Zero problems. I just opened the valve and let it flow into the filler neck when I needed fuel as others have said. You can fill from the either cap this way. I assume you talking diesel. JMHO

I have a 75gal KSH in-bed tank since 2010 with gravity feed, manual valve. I open the valve when ready to leave and close it at the end of the day, the only issue I have had was I left it open at night and when it got cold it drew in more fuel (shrinkage) then since I did not drive it the next day when it got hot it pushed fuel out the overflow of the main tank.

I have the RDS 40 gallon/tool box combo with the gravity feed. I love it when doing longer hauls. I do not have to worry about getting in and out of gas stations. Only issue i have had is if i run it open while the truck is full, it makes the check engine light come on. So when i get bellow half, i then open the valve.

This is my 3rd truck this has been in.

Installed this weekend, so far very happy.
It was weird, I put 10 gallons in to test it and no flow. I drove about 20 miles. Mid way stopped and changed the valve to what I thought would be closed, in case I was wrong.
No flow.
I got home and switched the valve back, went in figuring I would have to start troubleshooting later.
I went back out and believe it or not, the tank gauge was on E and the truck gauge had gone up.
I don't know if the valve just needed some back and forth action or what. I put 20 gallons in yesterday and it seemed to work well.
