Why Choose iFJF FD4616?
Diesel fuel contamination is the #1 cause of premature injector failure. The FD4616 dual-filter system ensures clean fuel reaches your injection pump and injectors. Unlike single-filter setups that leave the lift pump unprotected, this complete set guards the entire fuel path — from tank to combustion chamber.
Installation Tips
- Always replace both filters as a set for maximum protection
- Fill the new filter with clean diesel fuel before spinning on to reduce air in the system
- Hand-tighten then add 1/2 to 3/4 turn — do not over-tighten
- Prime the fuel system after installation per your engine manufacturer's procedure
- Replace every 10,000-15,000 miles or per your maintenance schedule
