  1. What keeps it from overfilling the truck fuel tank?

    1. I have a Aux. Tank in my trk with a inline 12 volt ball valve in the filler hose. When you fill the Aux Tank have it turned off so it doesnt fill your trk tank at the same time. As your tank runs down switch the ball valve on allowing the fuel to slowly fill you vehicle. Works great and the ball valve is fairly simple to install.

      Helpful?

    2. It has a unique yet simple float valve so when your main tank is full it blocks the flow of fuel. It works very good and I have experienced no problems with overfilling or leaks.

      Helpful?

    3. The secret is in the 90 degree fitting screwed into the larger barbed sleeve. Looking into the sleeve you can see that the bottom of the fitting is neatly crimped. Shaking it, you can hear a rattle. Using a small mirror you can see a small ball inside. When the level of the fuel rises in the stock tank, the ball floats up and blocks the flow of fuel into the stock tank. When the fuel in the stock tank drops, the ball falls and fuel flows in. It 's important to install the sleeve as close to horizontal as possible so the ball seats evenly

      It's similar in function to the ball (or hollow cylinder in a cage) inside a wet vac that blocks suction when the water rises too high

    4. You first would need to determine which type of fuel system your truck has, a pressurized or vented system. This kit has a rollover valve that works automatically with a pressurized fuel system. Most 2008 trucks had vented fuel systems which would require you use the manual fuel cutoff.

      Helpful?

  2. What is the overall lenght of the barbed fitting?

    I want to be sure that I have enough clearance between the ednge of fuel tank and truck bed to allow for the barbed fitting and 3/8" hose that will be connected to it.

    1. I had plenty of room for the fitting. I drilled straight through the side wall and looped it right into the adapter. My install on a 2004 Chevy Silverado

      Helpful?

    2. The overall length of the barbed fitting is 6 inches.

      Helpful?

  3. can you leave the valve open all the time so it fills ?

    or do you need to open and close it manualy?

    1. I purchased this kit and installed it on my 2008 GMC. It works well and does not overfill my tank. It keeps it topped up until all the fuel is used. I do not have to shut the supplied valve off as it does not over fill the tank. If I was leaving my truck parked for an extended time, I would probably close the valve. I have left it open for two weeks while the truck was sitting in my garage and both tanks were full with no spilling or overflow during that two week period of idleness. I am very happy with this kit and give it five stars. It was easy to install with a hole cut in the bed of the truck and cutting the fuel filler hose to install the supplied parts.

      Helpful?

    2. If your truck has a pressurized system then the kit has a rollover valve that works automatically. Most 2008 trucks had vented fuel systems. If you have this type you would need to use the manual fuel cutoff. You will need to know which fuel system your truck has.

      Helpful?

  4. What size are the various fittings, hose, etc.

    What size ore the fittings, hose?

    1. You specify what truck you are putting it on and they suppy the correct size fitting for your truck and year model. My kit came in for my 2008 GMC and my neighbor got one for his 2009 Dodge 450 and both kits fit fine.

      Helpful?

    2. The installation kit includes a 5/16" hose. The hose has a 2" adapter barbed on either end that will splice into the fill on the tank. It also has a 3/8" x 5/16" barbed manual shutoff.

      Helpful?

  5. Will this fit a 2011 Ford Super Duty?

    1. This diesel auxiliary conversion kit is for use with Chevy/GMC truck models from 1999 to 2010. Please see our item #3490901 for a diesel auxiliary conversion kit that works with Ford trucks from 1999 to current models.

    2. no you need the other model

  6. will this pass DOT inspection when installed

    1. you need to check with the local DOT office.

      Helpful?

    2. For information regarding DOT compliance please contact your state's department of transportation as DOT regulations can vary from state to state.

  7. Fuel tank outlet

    Does the transfer tank have to have a bottom outlet?
    The tank I have was designed for a electric fuel pump with a 3/8th top mounted fitting.

    Larry

    1. It uses gravity and you would have to have a suction for it to work if the outlet is on top.

      Helpful?

    2. Yes, this diesel install kit requires your tank to have a bottom outlet because it is a gravity feed type of application.

      Helpful?

  8. What size is the shut off valve and hose barb? Mine broke off 

    1 answer

    1. The installation kit includes a 5/16" hose. The hose has a 2" adapter barbed on either end that will splice into the fill on the tank. It also has a 3/8" x 5/16" barbed manual shutoff.

      Helpful?

  9. WILL THIS FIT A 2016 GMC PICK UP DIESEL

    1 answer

    1. The kit will work with 1999–2010 GMC models. It would not work with the 2016 version.

      Helpful?

  10. does the fuel outflow from the auxillary tank have space from the intake port on the inside above the bottom of the tank to avoid picking up gunk?

    1 answer

    1. The diesel kit is designed that it is drawing 1/2" from the bottom of the tank, so it do does not pick up anything from the bottom of the tank.
