3126e fuel filter location?

I have a 2002 Fleetwood Discovery 38D with a Caterpillar 3126e 7.2L.I'm getting ready to do engine maintenance. I have found the oil filter, fuel/water seperater filter but I can't find the fuel filter. I've talked to Fleetwood and Caterpillar and they have told me there are three filters. Any help would be appreciated. Thanks, Paul

I'll assume this is on a Freightliner chassis .

There might be a hidden strainer ( as per diagram and first picture ) just above the RR suspension air bag and the final fuel filter could be on the engine , as per the second photo .

Sorry I thought I had the fuel filter marked in the second photo , the red circle would be the location for the manual primer pump and the filter is directly below.

My 3126 b on 00 freightliner xc has a fuel water separator behind the rear drivers side dual , and a 2 micron cat filter(important!) on the engine top left side looking toward the rear.
