What's on the bottom of my fuel filter
Today I changed the fuel filters on my 2004 HR Endeavor ISC 330 hp. I removed the drivers side filter which is located in the area where the hydraulic jack reservoir is and had no problems.
When I attempted to change the filter above the starter in the passenger side I found the exact same filter as the one I just changed. A FS 1022 but the book says it should be a FS 1242 which is what I purchased.
In looking at the new filter (1242) there seems to be something that screws onto the bottom of the filter but that piece is missing. I'm thinking that perhaps the original owner lost it and just replaced the filter with a FS 1022.
Can someone tell me what screws on the bottom of the 1242 as I would like to bring it back to the way it was originally.
