DIESEL HELP AUSTRALIA DEVELOPS OPTIMUS PRIMER Helping aftermarket technicians to work around problems created by modern manufacturing techniques Diesel Help Australia has developed a number of cost effective tools to assist in diagnosing and repairs. It says one of the most popular releases is the Optimus Primer. Initially the Optimus Primer was innovated to assist with priming the air from the fuel system during replacement of a diesel fuel filter. Removing the air completely enables the fuel system to operate and the engine to start first time thus avoiding damaging any components. Many manufacturers have not included a hand primer on their engine systems, proving difficult for technicians to successfully ‘bleed the air.’ Even with electric or manual hand pumps fitted, considerable time costs or resulting damage have been proven. If a fuel tank is low and the electric pump is operated, the risks of seizing are doubled. As vehicle hand pumps age they may split causing air to enter during the priming process. As technology progressed, manufacturers began using a much cheaper option: pre-moulded

plastic pipes with a quick release fitting at each end. Without an ‘old style barbed end’, this proved difficult to connect a hand primer especially to the female end of the quick release fittings. There was no assurance to get a good seal without air entering during priming. The Optimus Primer provides access to over 30 individual diameters and angles of quick release fittings with a barbed sealable end, ensuring the user will have success connecting a hand primer to the vehicle’s supply without unwanted air entering the system during bleeding of the air. Air is one of the diesel fuel system’s worst enemies and has proven to be difficult to diagnose with a scan tool or any tool for that matter. Diesel Help Australia’s Clinton Brett has a populated list of fault codes when air is entering a diesel system. When adapting hose for liquid to travel particularly in a diesel to prevent air from entering, you have to be sure you have a good seal. By adapting clear hose to the barbed end of
the quick release fitting that has been matched to the system, the mechanic can run the vehicle stationary or take it for a test drive and look for air in the system. The kit itself can be seen demonstrated and purchased for a special training course price at Diesel Help Australia’s Ultimate CRD course around Australia and New Zealand. The Optimus Primer kit and/or replacement parts are available for purchase from www.dieselhelp.com.au
