My 1996 VW Passat Conversion

 

The first picture shows the WVO tank located in the carís trunk.Itís a 15 gallon water sprayer tank with a 6-inch opening that allows for easy pouring of oil into the tank.The flat section on top of the tank made it easy to plumb the heat exchanger and fuel pickup.This tank is thick HDPE plastic designed for chemicals and is very durable and holds up well to WVO.The heat exchanger is ĹĒ flexible copper tubing coiled and sealed with compression fittings.My original tank was purchased from Greasel.com and the heat exchanger in the tank was an automatic transmission cooler connected to the fittings on the outside of the tank with rubber heater hose.It turns out that WVO is corrosive to rubber and will eventually degrade the hoses causing coolant to contaminate the oil (very bad for the engine).All of the connectors through the tank are copper and brass, sealed with Teflon tape, and pressure tested prior to adding oil to ensure no coolant leakage.

 

The second picture shows the overall engine compartment.The filter in the lower right is for oil and contains a 10-micron water blocking element.Near the center of the picture is the solenoid valve for switching between the two fuel tanks.The brass valve over the alternator is for purging air from the fuel lines.This is a closed loop system where the excess fuel from the injectors is looped back to the input of the injector pump rather than to the fuel tank.For filter changes or anytime air gets into the fuel lines, the brass valve is opened to allow fuel to return to the diesel tank and air to purge from the lines.

 

 

The third photo shows a close-up of the fuel filter and the fourth shows the brass purge valve.

 

 

The fifth pictures shows the fuel selector solenoid valve, which is operated by the dash-mounted switch in the sixth picture.

 

 

Here is a close-up of the heater hoses and fuel line bundled together.This is Greasel.comís patented Triple Bypass Hose.I am happy with it and continue to use it, but it would be nearly as efficient to simply bundle standard heater hoses and fuel line.It consists of three Teflon hoses bundled together.The Teflon hoses are very rigid, but can be formed using heat, but I chose to use more flexible hose connected to the Teflon hoses with barb spicers in the engine compartment and trunk rather than trying to form the Teflon.
