Making a Conversion Happen
ROUSH CleanTech began the engineering and product development process for the propane autogas Ford F-750 in 2013.
“We wanted to make sure we understood exactly what the customer needed related to range/fuel capacity and how that would package with various bodies before we released in production,” according to Todd Mouw, VP of sales & marketing for ROUSH CleanTech.
Some of the applications/vocations that utilize this truck needed a clean cab-to-axle (CA), so ROUSH CleanTech released a dual short tank configuration that offers 49 usable gallons but does not interfere with applications such as beverage delivery with a drop frame.
“We approach the development process in a manner similar to an OEM related to design, validation, testing, and a continuous loop of customer input back into our engineers to ensure those requests were being incorporated where possible,” Mouw explained.
Due to careful planning and communication, there aren’t many challenges once production starts.
“Once we get to production the process is pretty straightforward. We have a vehicle special order (VSO) option where the frame rails are pre-punched in the locations where our tanks mount. This helps reduce installation time and does not impact the integrity of the frame. Our order-to-delivery time is typically less than 120 days, which is pretty good for a medium-duty truck,” Mouw said.
The process for a fleet to convert an existing model is also simple.
“A fleet will order through their Ford dealer or leasing company with the VSO option code. They advise which of the three tank configurations are best, and the upfit is either done at ROUSH or at a qualified vehicle modified (QVM) approved upfitter if it is closer/more convenient for the body installation,” Mouw explained.
ROUSH removes all of the base gasoline components and then replace them with purpose built liquid propane components such as billet aluminum fuel rail, fuel injectors, stainless steel fuel lines, fuel tanks, and the company’s proprietary calibration to ensure the vehicle operates seamlessly on propane autogas.
