Switching Jetta TDI to dual fuel?
If I add a second fuel tank just for waste vegetable oil (WVO) and run a line from that tank to the existing diesel fuel line (with a two way solenoid valve), do I need a dedicated fuel pump for the WVO or will the suction be enough to feed the engine? I figure it would be easy to put a nalgene carboy in the trunk, run copper tubing to the existing fuel line under the car, and install a good two way valve. This would allow me to run WVO once the engine gets warmed up and switch "on the fly". It would also reduce the chances that I'd get stranded somewhere if I do have problems with the WVO. Would blanking off the diesel fuel pump while it is running be a problem?

I would say that yes, you would need a lift pump for the WVO plus you would probably need to heat the WVO before using.
Try looking at WWW.GREASECAR.COM for a few hints and tips plus thay sell installation kits.
