Boyd Aluminum Gas Tank

This Boyd Aluminum Tank includes a 41001 in-tank EFI assembly with Aeromotive 340 pump. The pump fitting on the plate is threaded for a -6 ORB fitting (9/16-18 O-Ring).

Each tank is intended to mount to the bottom of the frame rail. It is not necessary to remove the “X” shape rear cross member as the tank will sit below it. The mounting tabs will require drilling and trimming to clearance frame rivets and bed mounting holes.

If you have removed that cross member when adding 4-link coilover or airbag kits, it is possible to mount the tank to the top of the frame rail. Additional fabrication to the bed floor will be required.

  • 3” tall twist cap bed filler
  • Tank dimensions: 31.5 x 24 x 10 inches
