The mounts on this 2.2 gallon, heavy gauge steel gas tank are stock fitment on 2004-2006 Harley-Davidson Sportsters. This is a flat-bottom tank, as opposed to modern XL gas tanks that round over at the bottom.

The center mount gas filler bung that accepts a thread-in Harley-Davidson style gas cap, a stock-style 22mm H-D style petcock (Left side when sitting on bike), and a vent tube that is soldered shut. To run the vent tube just melt the solder out, though if you are running a vented gas cap this vent tube is not needed. The tank shells are stamped from 1mm (approx. 19 ga.) steel. Take a look at the photo gallery for the dimensions on this tank.

Note: It is highly recommended to fit your gas tank to your bike before painting. Check for clearance or mounting issues as different combinations of triple trees, risers, and handlebars may cause clearance issues when turning. Tanks are pressure tested but it is highly recommended that you or your painter pressure test it again before painting; it's cheap insurance!
