I still don't see any value in having it drop down to tank level, but I don't think you want any low points in that line.

I think I will add a riser like yours to my trunk mounted tank, just for grins. My vent line will run up to the top of the trunk, only about 6", then drop down to a drain fitting through the floor.

Roger, at this point it's trial and error with the hose held only by cable ties. What I did is put a basic liquid trap in the line. If it doesn't work, then I'll see what else can be done including your suggestion. Unfortunately I'm trying to work with a fully upholstered car, including the trunk and really don't want to pull it out unless that's the last resort
