Hi all, this is my first post as my wife and I just purchased a Gemini 23TB. I appreciate the helpful comments and have had similar issues as most of you. We are diesel engine virgins so I'm trying to get up to speed on maintenance. A friend who is a long time diesel truck owner mentioned the importance of purging the fuel/water separator regularly for various reasons. So far, I've not been able to locate this device. You tube videos for the standard Ford Transit show it being roughly under the driver's seat mounted to the chassis (from underneath the vehicle ). It doesn't appear to be there from what I see. Anyone familiar with its location? Thanks in advance!
