This Chase Bays 10AN Pump Feed Adapter is not only the best way to convert your pump feed to -10AN; it fixes a major issue with the stock leaky unit. It is machined from 6061 billet aluminum with Mil-Spec Class 3A threads, anodized with our signature UV proof satin black finish, and laser etched with our CB logo.
The adapter is built as a swivel design so you can clock it however needed. We use a harder durometer and stronger viton material for the O-Ring than Mazda so aside from the obvious 10AN upgrade, even the seal is stronger and more heat resistant.
This is a "press-in" style adapter. All you do is remove the stock piece with strong pliers or vise-grips, then tap this in gently with a deep 22mm socket.
