When you're setting up a custom fuel or oil system, you often need to pass a hose through a firewall or a component housing. That's where a bulkhead fitting like this one from Russell comes in handy. It creates a secure, sealed pass-through point for your -4 AN hose, ensuring a clean and reliable connection.

This particular bulkhead nut is precision machined from lightweight 6061-T6 aluminum, which is a strong material for this kind of application. It's designed to maintain a positive seal even at maximum operating pressures, so you don't have to worry about leaks. The Endura finish gives it a clean look that complements many engine bay setups.

This fitting has a 7/16 inch -20 thread size, which is common for many fuel pumps, oil pumps, and other engine components. It's a straightforward part that makes a big difference in getting your custom lines routed correctly and securely.
