    I have a 1962 chevy c-10, the spare tire carrier has been removed. Can I you this tank in my truck, it’s already set up for a side fill tank.

  • Johnny says:

    How many gallons does this hold?

  • Donn says:

    do you also sell this tank in the poly?

  • randy says:

    i have 71 c10 does this kit comes with the necessary fuel lines or do I need to buy a kit for it?

  • Steve says:

    top fill tank, any diagrams and/or directions where to drill fill hose hole? I would like to have this done prior to mounting the bed. Just trying to keep it simple. (1966 swb fleetside)

    • BROTHERS says:

      Unfortunately there is no standard on where to drill the holes because it could be slightly different on each application. It is recommended to mount the bed first, then drill the holes to make sure they are right on. You wouldn’t want to mount everything then find out that the hole is slightly off alignment.

  • Michael Liljenquist says:

    will these work for 63-66 suburban/carry all?

  • Esteban Gonzalez says:

    How much clearance is there from the tank to the floor. I have a 72 chevy pickup long bed. The tank look pretty close to the floor on the picture!

    • BROTHERS says:

      The example above is using the side-fill tank. Yes, it is close to the floor (similar to everything else at the bottom of the truck). The side-fill tank sits above the frame-rail by approximately 3/4″ to 1″. The top-fill version of the tank fits flush with the top of the frame-rail.

      • Garcia says:

        Do I have to cut into the bed Rails or will it fit flush with no cuting on the side mount gas tabk.

      • Rusty says:

        So the top fill hangs lower? 1970 C10 with -4″ Coil springs. Do you think I will have the clearance with either tank?
        Thank you

        Staying with the same question, I have a 70 LWB that I want to use your conversion kit to move it from a LWB to a SWB and add the C-Notch kit. If I end up lowering the truck 5 1/2 inch’s how close will the tank be off the ground? If there a better tank to use when lowering the truck? Does this tank hang lower then the rear bumper?

        • BROTHERS says:

          We have this exact conversion on our Project Eighteen8 we built last summer. You will have no ground clearance issues with the tank once the truck is lowered and shortend. As a mater of fact, our video on YouTube shows us installing the tank on Eighteen8 AFTER it was already shortened and lowered, so you will be able to see the answer to your question. Here’s a link to the video https://www.youtube.com/watch?v=NQ33sH3unFA

  • DANIEL Fierro says:

    Does the sending unit that comes whit it work for a tbi engine?

    • BROTHERS says:

      1960-66 comes with a 30 ohm sending unit. The 67-72 comes with a 90 ohm. There are no provisions for a pump so you’ll have to run an external pump. Hopefully this helps but if you have additional questions please give us a call.

  • Don says:

    I have a 1966 suburban carryall and would like to upgrade the gas tank to a larger one with internal fuel pump and return inlet for a fuel injection conversion I am planning. Do you have a tank that could be used for this purpose?

    • BROTHERS says:

      Unfortunately we do not have a larger tank for that specific purpose. Please give us a call to discuss this. The aluminum 63-72 truck gas side fill tank could possibly work for your application, but it would be best to call & we can figure out the best options for you.

  • sam Pearson says:

    I have a 1968 Long Bed stepside Truck. The top fill tank I received from you seems to have a conflict with a frame cross member behind the original rear end. The cross member seems to be removable since it is not as rigid as the frame rails. Is this usual in this instillation? If frame cross member is removed is there any significant problem that may occur.

  • Joel turner says:

    What are the dimensions of the tank?

  • marlin says:

    On a side fill how far does the tank hang below the bottom of the frame?

  • Mark Jeske says:

    Got a 66 C10 pickup. Would like to replace present gas tank with one to go under the bed. Will these tanks work? And which would be better- side fill or bed fill?

    • BROTHERS says:

      We offer several options for converting to a rear mount gas tank. You can give us call at 800-977-2767 and we can discuss the specific differences.

  • Dale Lawless says:

    I have already purchased the under-bed tank (pt. #GTPDS66) several years ago and was unable to see any possible mounting configuration that would not interfere with the bed cross member directly beneath the wooden floor of my ’66 short-wide. I even stacked 2″ spacer blocks between the frame rail and the tank flange to lower the tank. No-Go. short of approaching a competent welder to refabricate the overall depth of the tank, I am totally stymied. Any help would be appreciated.

    • BROTHERS says:

      You will need to take a section out of the interfering bed cross sill to allow the gas tank to seat against the bottom of the frame so the straps will connect. If you need assistance, give us a call at 800-977-2767.

  • Fernando Perez says:

    Will this tank fit on a 1969 G20 Sportvan?

  • tony zavala says:

    how will the sending unit wire connect to existing original wire?

  • Forest Kehl says:

    are you able see the tank hanging after install from behind the vehicle?

  • Forest Kehl says:

    on my 1967 chevy pickup , I was wondering if I install the 67-72 suburban gas tank if you can see it hanging down from behind the vehicle?

    • BROTHERS says:

      Yes, it can be view below the rear bumper. The tank was not designed for max ground clearance, if that is needed I would recommend one of our aluminum tanks. They measure only 9″ deep.

  • Abram Robles says:

    I bought a tank for my 72 c10 this weekend but the straps don’t seem right. Is it possible I got the wrong straps in my box?? They are a L shape black strap

  • Tony Taylor says:

    What size is the rubber hose for the fill neck

  • Alex says:

    Hi there,
    Do you have the measurements of the tank?

  • Joe says:

    I bought the top fill tank with fuel sender and mounting kit. I am just wondering what the small tube on the side is for. Thanks in advance.

    • BROTHERS says:

      It is a vent tube for expelling gas during fuel fill/sloshing. Connect a hose to it and mount it as high as possible with a loop to prevent fuel spilling during acceleration/cornering.

  • Kelly says:

    Dose the sending unit have the wiring kit with it or would i have to run wires to it.

  • Ross says:

    70 GMC LWB, After I installed the tank, I’m having problems getting fuel to the engine. What did I do wrong/not doing?

  • Juan Ponce says:

    I have a 1970 pickup truck the item description mentioned side fill only! Can it be mounted to any side? I need to mount it to the left side

  • Larry Anderson says:

    I just ordered your 64-65 Chev. Long bed too Short bed conversation kit is there anything else I need with this tank?

  • Scott Milgrom says:

    do you have instructions on installing it in a 1970 C-10? The straps i have seem to be wrong and I am trying to see if there is a step i am missing.
