I am new to VW diesels, and was wondering how to prime the fuel system on the ecodiesel. My diesel experience comes from my 300D, and I am not seeing a similar system. I am about to start running grease and won't put any in there until I can change the filter. Thanks for the help.
fill the filter with fuel, it will give you enough fuel to prime the lines from the tank up. I've never ran WVO so I am not sure once you do when you do start to run it. I'd guess warmed up WVO.
So there is no manual primer pump on the VW IDI 1.6? Is that orange plastic part that is cottered to the top of the filter on the return line essentially a bleeder?
Wat is best to install for this exact purpose is those primer inline bulbs commonly found on MOST outboard boats.
The fuel will flow with zero restriction.. but when squeezed it is a inline siphon

Right, no bleeder like the MBs. That cotter pin thing you are talking about controls the temperature of the fuel I'm told. When the fuel is cold it returns it to the filter to go back to the pump but once it gets to a certain temperature then it cycles it back to the tank.

Correct, and a expensive little bugger it is, too. Be nice to it...

would it be incorrect to assume that the engine would run without it? Especially given where I live, in coastal Georgia, if it were to fail.
I deleted it from my car. It's more headaches then it is worth in my opinion.
