I've been looking for someone who has a W115 300D ! I thought Ken300D had one but it is you that I saw the tag "W115" at the end of your post!
How do you make your pickup connection for your pump to run Diesel Purge through on a W115? The return is a piece of cake, but which line do you use for a pickup? I thought maybe the line that comes into the hand pump, but that wont work either. Must be one of the other ones. I'm just a coward and don't want to break loose any fittings that I dont have to!
Anyways, I just wanted to see how someone else with a similar setup does the hookup! TIA, Tom
