Fits for Ford 6.0L and 7.3LPowerstroke Diesel High Pressure Oil System IPR Air Test Tool Special KIT. Scope of application: Fits for Ford 6.0L – 7.3LPowerstroke Engines, Includes 7.3L Powerstroke High Pressure Oil System IPR Air Test Fitting. Advantages With This Tool:NO Scan tool or IPR driver tool is required, Leaks of ANY size can be detected, engine builders can quickly verify that an engine has no high pressure oil leaks before installing the engine into the vehicle where repairs are much more difficult. Allows systems with the latest updated standpipes to be tested. This tool takes the place of the IPR valve meaning that the system can be completely sealed so that even the smallest leaks can be detected. The heavy-duty hydraulic hose is rated up to 5,300 PSI. Remove the IPR valve and thread in the tool, hand tightening using the hose is sufficient. Connect shop air and listen for leaks. To locate the smallest leaks close the shutoff valve on the tool to seal the system. Be careful:If desired a scan tool can be used to monitor air pressure in the system by observing the ICP sensor reading. This is not a required step. To prevent costly repairs we recommend air checking every 6.0L for high pressure oil leaks after any part of the system has been disassembled.
