To successfully prime the engine and avoid damage to the system, it’s very important that you only use DD approved priming devices. Any air trapped in the fuel system can hinder ignition, destabilize fuel pressure, or damage the fuel pump.
So what is the best Detroit Diesel approved fuel priming device?
To effectively prime a Detroit Diesel DD13 or DD15 engine, use the ESOC 455 fuel primer. This pneumatic fuel primer meets Detroit Diesel OEM requirements by delivering 95 PSI of fuel pressure for 2 minutes.
With a powered DD approved fuel priming device like the ESOC 455, you can prime a DD13 or DD15 fuel system in minutes, successfully start the engine every time, and eliminate the mess and hassle that comes with using a hand pump.
When the fuel supply is emptied (running the engine dry) or engine maintenance is performed, air can get into the fuel system. Pockets of air in the closed fuel system hinders the ability to pump fuel from the tank into the injection ports – therefore impeding successful ignition.
Hand priming pumps can be a good option for your casual priming jobs. If you operate a single truck and just need something to prime the engine after a filter change, a hand priming pump can get the job done on many diesel engines.
For the busy maintenance facility, fuel priming devices like the ESOC 455 are worth more than their weight in gold because of the time and frustration they save.
The priming procedure is as follows:
Step 1: Fill up the ESOC 455 fuel holding tank
Insert draw tube into fuel tank
Connect the suction tube hose to the draw tube
Connect air supply to the machine using quick-connect fitting
Turn on drain switch
Open the flow control valve
Monitor the orange ball float as it approaches the “max-fill” level
Close the flow control valve to stop filling the holding tank
Turn the drain switch off
