Impervious to cracking like the OEM fuel filter cap
CNC Machined from solid aluminum billet
Features a 1/8th" NPT port for fuel pressure testing
A cracked fuel filter cap can lead to air in the fuel system. That can result in hard starting or potential fuel injector issues. 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 Fuel Filter Cap. Constructed from a single solid aluminum billet, the Sinister Diesel 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.
Kit Includes:
(1) Sinister Diesel Fuel Filter Cap
(1) O-Ring
