Great info here. Its helpful to read this just to remind me why its important to maintain good habits while greasing.

I was just curious of everyone's opinion on the placement of components in there om61x mercedes diesels. Has anyone else had problems running your main veggie oil filter on the vacuum side of the lift pump like the greasecar design instructs?
In my first post I tried to describe my system using a third valve so the filter can be on the pressure side. This is the only way I have been able to run WVO in my 240d without a designated 12v wvo lift pump.

Any thoughts? I'll try to dig up some diagrams.

Also JB3, that 3 tank design sounds interesting! What is the additional advantage of a third tank. My trunk is dedicated to hauling oil so it might make sense for me to do something like that.

The first diagram is greasecar's 2 tank mercedes kit. The second diagram is the sun wizard 2 tank routing that i used.
