Reproductions of the 3-1/2 gallon Knucklehead gas tanks as used from 1936–1946, made to accept the Skull/Cateye dashplate and cover plus hand shifter gate. The 1936-1939 version accepts the stock type left and right petcocks, the 1940-1946 is made for push-pull gas valves and features all mounts for emblems and strips.
All gas tanks by W&W Cycles are delivered unpainted and unsealed. Before the paint job and final installation please consider the following:
- We consistently receive tight gas tanks from the manufacturers, both Custom and OEM replacements.
- Problems mostly occur during or after installation. Hence, before a pressure test and before painting - a probationary tensionless installation is highly recommended. Any leverage on the tank mounts spells trouble. Better use our selection of small parts.
- To avoid corrosion always fill your tank to the max during longer downtimes or seal it on the inside.
