HD STOPPER KIT, ALUM (SUL478)

HD Aluminum Stopper Kit is a stopper assembly designed to seal high-pressure fuel tanks used in racing and bladder-type systems. Built with red aluminum construction, it includes both glow-white stoppers for visibility and black stoppers for gas or diesel fuels, plus brass stoppers in 1/8-inch and 3/16-inch sizes.

Designed for all fuels, this kit provides reliable sealing under demanding conditions. The color-coded stoppers and brass sizes offer flexible fitment for a range of tank ports, while the durable aluminum construction delivers longevity in race-day environments.
