A cracked fuel filter cap can also cause a fuel leak, which is definitely a bad idea on a hot engine. Never worry about that again with a Sinister Diesel Lower Fuel Filter Cap. Constructed from a single solid aluminum billet, the Sinister Diesel Lower Fuel Filter Cap is far stronger than the OEM plastic cap. It's anodized in Sinister Blue for corrosion resistance and features a 1/8th" NPT port for testing fuel pressure. Features:Impervious to cracking like the OEM lower fuel filter cap, CNC Machined from solid aluminum billet, Features a 1/8th" NPT port for fuel pressure testingIncludes:(1) Sinister Diesel Lower Fuel Filter Cap, (1) O-Ring.
