when i decided to convert my car to run on WVo my intention was to convert it the conventional way, the improve on it for a for reliable system. there is a logical reason for more air leaks on conventional WVO systems in a Mercedes. when you run on vegetable oil, the fuel system is rearranged so that it pulls fuel through all the filters, etc. a connection under suction is much more sensitive to air leaking in, than one under pressure.

back on subject:

are there any diagnostic tests i can do to tell where the problem is? so far all you guys seem to do is speculate

Thanks,
Ethan
