❓ FAQ
Yes. The kit ships with one FD-4596 element, one 6061-T6 billet aluminum cap and two fuel-resistant O-rings, so the element seal and the cap seal are both replaced in one job.
The cap fits the factory fuel bowl on 1999 to 2003 Ford 7.3L Powerstroke V8 engines, including the 2001 F-250 and F-350. It turns on with a 1 inch hex and is sealed by the O-ring supplied with the element.
The factory cap is molded plastic that goes brittle after years of heat cycles and vibration, and it splits when a socket is cocked on the ribs. A 6061-T6 billet aluminum cap is cut from solid bar and does not age the same way.
FD-4596 crosses to Motorcraft FD4596, Ford F81Z9N184AA, Baldwin PF7698, WIX 33818 and Fleetguard FF5418. The element is rated 10 micron at 98% efficiency and drops into the factory bowl.
The cap can be reused only if it is not cracked or warped, but the cap seal is the O-ring that arrives with the element, so the old ring must be discarded. A cracked or warped cap lets air into the fuel and causes hard starting.
