If you own a 2003-2010 Ford truck or van with the infamous 6.0L Powerstroke diesel, you know the fuel filter housing can be a pain.

Maybe the cap is cracked, or the o-ring is leaking and letting air into the system.

Here's the fix: a brand new fuel filter cap and o-ring kit from Mid Valley.

It's a direct replacement for the factory part, with the OEM number 3C3Z9G270AA.

It also crosses to 904-209CD and 904-209.
This kit includes the black plastic cap and the all-important o-ring that seals it.

It's made from plastic, and it's designed to fit the 6.0L V8 diesel engine.

It fits a ton of models: F-250, F-350, F-450, F-550 Super Duty, E-Series vans, and even the CF500 from model years 2003 to 2010.
The outlet diameter is about 3 inches.
It's a simple part, but if that cap is broken or the o-ring is squished, you'll get hard starts and poor performance.
Swapping this out is an easy DIY job that can save you a headache.
Mid Valley gives a 1-year warranty.

Get your fuel system sealed up tight and keep that 6.0 running.
