Okay, the 2005 Jetta TDI is a Pumpe Duse rather than the post 2003 models. If it cannot run on biodiesel what needs to be changes like fuel lines and alike. Thank you in advance.

Been thinking about using it but have heard it messes up the rubber fuel lines.

i have been doing some research on it and i’m considering buying an older mercedes. from what i understand the only conversion it really requires is new fuel lines but my main concern is how realistic it is for me to make it in my garage with used vegetable oil from a restaurant.
what is the main difference between biodiesel and wvo? i’m confused.

Any companies that would sell Biodiesel Fuel Lines would be appreciated.

Thanks in advance! 5 Stars!
