Frisco mount Sportster tank for custom use. Tank uses cam lock gas cap and has threaded ports for either 3/8" petcock or 1/4" petcocks.
Even though these tanks are pressure tested from the factory, we recommend sealing any custom tank with POR15 or Kreem Tank Sealer before painting. It is cheap insurance. Also, assure there is no stress on the tank or mounting hardware when the tank is mounted.
