I've got a few of these filter assemblies. These are the dual canister fuel water separators model 751000MAX. They have a restricton guage and a four way valve so you can run one filter until the gauge reaches a certain restriction value then switch to the other filter, or you can run both filters at once or turn fuel flow off. Or you could break the assembly down and have two independent filters. You can drain the bowls from the bottom and the filter pulls out the top. You can put filters down to 2 micron or up to 40 micron in them. I'll be running one in my truck with a pair of 2 microns in it. These are marine grade units and cost around $1000 new. $400 each plus shipping. or best offer... more pics available. Dave
