1963-1972 Blazer/Suburban Gas Tank Installation

BROTHERS Blazer Suburban Gas Tank Kit is an easy to install kit designed as a direct replacement for the factory steel gas tank found on the 1967-72 Suburban and the 1969-72 Blazers. This kit can also be used on the 1963-72 pick-ups. This requires adding a fuel line down the passenger side frame rail and installing a filler neck assembly as described below. On the pick-up trucks, the spare tire must be relocated and the spare tire bracket removed. Also some vehicles require that a bed cross sill be trimmed for clearance. The tank is now reproduced in rust-free poly-ethylene for a trouble free, long lasting installation

    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.

  • 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.
