914Rubber Steel Gas Cap Seal for Early Porsche 914 (1970-73)
Eliminate fuel vapors in your Porsche 914 with the 914Rubber Steel Gas Cap Seal (part number 343.201.551), designed for early 914 models from 1970-73. This reproduction seal fits the larger steel gas cap used on these years, ensuring a tight, odor-free seal for the fuel filler neck. One seal is required per car, compatible with 1.7L, 1.8L, 2.0L, and 914/6 models equipped with the steel cap and metal overflow dish.
PMB Performance, with over 20 years of Porsche 914 expertise, has partnered with 914Rubber for nearly two decades, selling more 914Rubber SKUs than any other retailer. Crafted from solvent-resistant rubber, this seal withstands gasoline exposure, moisture, and front trunk temperatures up to 160°F, unlike factory seals that dry out and crack, allowing fumes to escape into the cabin. Its 65mm outer diameter fits precisely within the steel cap, preventing leaks that could harm the 16-gallon tank or the 914’s 1,980-lb chassis, as noted on pmbperformance.com.
A degraded seal can cause fuel evaporation, trigger smells in the front trunk, or allow water ingress, risking corrosion in the filler neck. Installation is straightforward, pressing into the cap’s groove, and pairs well with the 914.201.893.10 expansion tank gasket for a full fuel system refresh. Regular inspection during tank maintenance, as advised in Pelican Parts’ 914 fuel system guides, prevents issues.
