This is the water separator drain plug upgrade for the HFCM (Horizontal Fuel Conditioning Module) on all 2003 to 2007 F-Series 6.0 Power Stroke Diesel applications. This is new and OEM from Ford. The plug uses a 6mm allen hex and knurled at the outer grip area of the plug. It uses the long retainer to keep itself from being dropped. This also helps the draining process by keeping the water and fuel from draining onto the front driveshaft on 4 x 4 models. It does come with a new o-ring also. Shipping options and costs are available once items are placed in the shopping cart and based on your zip code.
