I just bought a used jetta TDI, equiped with vegi oil tank in the trunk. My diesel fuel is not going back to the fuel tank, it's being reused by the IP due the the new fuel hose layout for burning vegi oil. The reason why is so that vegi oil wont go into the fuel tank. Is that OK? I mean VW engineers had some sort of reason for the return diesel fuel to run back to the fuel tank. Granted I live is So Cal. Should i change it so that the diesel fuel goes back to the fuel tank like it was stock?
