The Vibrant Performance -10AN Fuel Cell Bulkhead Adapter Fitting (MPN 16894) is a through-wall connector that ties a fuel cell or tank to the rest of an AN-plumbed fuel system. It mounts through the cell wall and accepts a -10AN line on the working side, giving builders a clean, serviceable pass-through instead of a permanent welded bung. This is a part for anyone running a dedicated fuel cell on a race car, off-road truck, or street build who wants the larger -10AN bore for high-volume pumps and forced-induction fuel demands. It belongs in the same plumbing kit as your hose ends, unions, and feed line.
Bulkhead fittings work in two pieces: the main body passes through a drilled hole in the cell wall, and a retaining nut clamps it down from the opposite side, sandwiching the panel between sealing surfaces for a leak-free joint. The -10AN size is rated for high-flow applications where a -6 or -8 line would choke a serious pump. This part runs an 8-inch length per manufacturer specifications, which lets the body reach through a thick cell wall or sump pickup and still leave thread engagement for the nut. Pair it with matching -10 straight hose ends and -10AN union hardware so every sealing surface in the run matches and torques the same way.
Reach for this fitting when you're plumbing a fuel cell outlet, return, or vent and want a removable bulkhead instead of welding. It suits drag and circuit cars, sand and rock crawlers, and street builds that have outgrown factory tank plumbing. Drill the panel, set the body through the wall, run the nut down on the back side, and connect your AN line. When you're done, cap any unused ports with a matching -10AN port plug. Browse the rest of our fittings, hoses, and valves to finish out the system with line, clamps, and valves sized to match.
It passes through a drilled hole in a fuel cell or tank wall and clamps in place with a retaining nut, creating a sealed, removable pass-through. The -10AN end then accepts a -10 hose end so you can connect fuel feed, return, or vent lines without welding a bung into the cell.
The larger -10AN bore moves more volume, which matters with high-flow fuel pumps, large engines, and forced-induction setups that demand steady supply. If your pump and lines are sized at -10, the bulkhead should match so the through-wall connection isn't the restriction in the system.
A bulkhead fitting seals by clamping the cell wall between the body and a retaining nut on the opposite side. Confirm your kit includes the nut and any sealing washers for your -10AN setup, and match every hose end and union in the run to the same -10AN size.
