Transitioning a fleet to propane autogas is easy. The real challenge is converting a work truck’s gasoline fuel system to operate on propane autogas — which is handled by the manufacturer of the fuel system. 

In this piece, ROUSH CleanTech, which designs, engineers, manufactures, and installs propane fuel systems for Ford commercial vehicles and Blue Bird buses, will illustrate how to convert a Ford E-450 truck to run on propane autogas. It takes a qualified, trained technician roughly 12 hours per vehicle to complete these steps. 

Step 1: Remove the factory fuel tank to install the propane tank.

Step 2: Install the fuel lines and fuel filters inside the frame channel.

Step 3: Disconnect the original fuel pump relay and attach the additional ROUSH CleanTech relay.

Step 4: Attach the fuel lines to the tank.

Step 5: Now, technicians remove the original fuel rails connected to the engine and install ROUSH CleanTech fuel rails and the Fuel Rail Pressure Control Module (known as FRPCM).

Step 6: Install the Smart Relay Module and new wire harness.

Step 7: It’s now time to flash the Powertrain Control Module with ROUSH CleanTech software.

Step 8: The recently installed components are tested for propane leaks.

Step 9: Lastly, the vehicles undergo a vigorous inspection and certification process.
