Green Machine Fuel Systems specializes in waste vegetable oil (wvo) conversions for the ford powerstroke truck items needed for a conversion for a 6.0 or 7.3L Ford: Fuel Pump, fuel filter with water separation capabilities, fuel tank, heated fuel lines, heated fuel pickup, fittings, vac gauge, two relays, 10 gauge wire, 10A fuse block, switches, hose clamps, check valves (3). You will need to install check valves at the two stock fuel lines that feed the head. They are located at the drivers side front and the passenger rear on a 7,3L. on a 6.0L they are both in the front. This will be the only modification to the stock fuel lines. The locations where the New fuel system will feed into the motor are opposite the stock locations, for a 7.3L, drivers rear fuel rail and passengers rear. and a 6.0L are both at the rear. The dedicated vegetable oil pump will be switched on when the stock pump is switched off using relays. you should bring a new 12v feed from the battery to feed the relays. the 3rd check valve needs to be installed somewhere between the new fuel pump and the motor. you will need a vacuum gauge installed between the pump and the fuel filter to alert you when the filter needs changing. 6.9L and 7.3L idi PRE powerstroke 7.3L powerstroke
Methods of conversion Two methods Separate fuel system and pre-stock pump method Pre-pump method would use a 6 port valve to switch prior to a single pump, the stock pump (will fail sooner than later) or a more robust pump This method will run both diesel and WVO through the stock fuel filter and have long purge times. The positives would be simplicity and cost. Installing a completely separate fuel system is the best choice although more difficult to install and more expensive. The pros would be shorter purge times and reliability in the event of Either system failure The costs of this method are associated with the installation requiring that all four ends of the engine block need to be accessed and a wvo fuel pump must be used. 6.0L powerstroke |
