Your 6.4L can make some great power, and it's a great unit, but it's not impervious to issues, which is why we've brought you this Sinister Diesel billet fuel cap. 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.
Part Number: SDG-FFC-6.4
- Impervious to cracking like the OEM fuel filter cap
