An AN10 fuel cell fitting for tank connections that need to move real volume. High-power engines, methanol setups and multi-pump fuel systems all demand more flow than an AN6 or AN8 tank fitting can comfortably supply, particularly on the suction side where restriction causes cavitation and pump failure. This fitting mounts to the fuel cell and presents an AN10 male flare externally, so the tank can be plumbed with standard braided hose and AN hose ends for a clean, inspectable joint. Check that the flange dimensions, bolt pattern and sealing arrangement match your fuel cell before ordering, and use fuel-compatible seals and hardware when fitting.
