The Valkyrie uses 2 of these kits, one between carbs 3&5 and another between carbs 4&6.
This kit is 1 CNC-Machined tee fitting with 2 Viton-GF o-rings. It replaces the original Honda part named " JOINT SET, FUEL 16024-MZ0-000 ". The Honda part is Glass Filled Nylon, but Red Eye decided to go with 6061 aluminum, lightly anodized. We're not sure why Honda chose the color Poo-Poo-Brown for their fitting, but we have brazenly departed from that. The o-ring grooves are smooth and bright on the Red Eye fitting, so a short visual inspection tells you whether it is going to hold fuel.
