  • Material: Stainless Steel. Chrome steel Includes rubber gasket.
  • Be sure fit of tank, mounting hardware, petcocks and gas caps are true prior to painting. No stress is applied to the tabs when bolting them to the frame, this can lead to cracking of welds. If needed, use leather or rubber washes to shim between the tabs and the backbone to ensure an even fit. Do not sand seams or welded edges of gas tanks, if needed use a thin spread of body filler prior to painting.
  • Easy Installation. No additional hardware required.
