For pre-83 bajonet style gas cap (not included). Scaled down XL Sportster tank; 1.7 gallon (6.4 liter); for 22mm petcock (not included); with Frisco style low tunnel. A scaled down version of one of the nicest fuel tank styles for classic customs, the XL Sportster. Equipped with a low tunnel so they’ll sit high on the frame for the right Frisco style look. Still it holds 1.7 Gallons, which is a reasonable amount of gas considering the size. Comes with a 22mm petcock fitting. Note: It is advised to pressure test, seal and test fit all tanks before tanks are painted and installed. Some tanks are painted, but this coat is applied for rust prevention during storage only.
