45-degree push-on hose end in AN8 (-8), pushing straight onto socketless hose and gripping the barb without a clamp or crimped socket. AN8 suits main fuel feeds, turbocharger oil drains, breather and catch-can plumbing, and cooler lines that need more bore than an AN6 run can give. Forty-five degrees is the most-used angle on any build, steering hose around brackets, rails and pulleys while keeping the bend radius easy. Gravity-fed lines such as turbo drains benefit from the extra bore, since drainage depends on volume rather than pressure. Ordinary rubber hose will not grip the barb correctly, so use hose specified for push-on ends.
