StumFAB’s Universal OB Tunnel Oiler System works on most nitro powered outboard tunnels. Made in the USA from 6061 billet aluminum. Comes with everything pictured, you will need to add your own fuel tubing to connect the oiler to your lower unit. We recommend using Loctite (or similar) on ALL fasteners. Final product may vary slightly from the photos due to constant material and manufacturing changes. It is recommended to use a small zip tie around the rubber cap to assist in keeping it on the oiler tube. It is up to the end user to trim the cap as they see fit. Some users prefer a hole where as others prefer a slit with a razor blade.
