Serpent Angled Pressure Nipple

(Source: MyTSN)

Suitable for all Serpent fuel tanks is this convenient two-piece right-angled back pressure nipple. Attached to the fuel tank lid in the standard position, this product allows the back pressure tubing to run to the back of the tank instead of directly out to the side. This removes the need for a large cut out around the fuel tank and stops the fuel tubing from catching in the body when the fuel tank lid is opened.
