it's the one on the top left, which doesn't have a 'see thru' water cup, but does the same job - with a drain petcock at the bottom. I may have said Fleetgard, as that was the Primary Filter, but this replacement for the fuel water separator is Baldwin, since the other brand that Freightliner/Thor adds was not available. This fuel water separator is not a filter that Cummins says that they provide with their ISB6.7L engine that go into motorhomes, but that Freightliner/Thor adds them later. News to me, but Cummins could find no 'Cummins' fuel water separator like what was on the engine originally. Oh Well.
I will say that in all our travels and over 100,000 miles, I've never seen water in it or had to drain any. The first one was changed at about 15-20k miles, this one at 107,000...
