systems, my group leader and I had a light bulb go off while i was messing with the 7.3l injecor tester (porta power with engine oil). We had a fitting and hose made to fit the icp sensor in the oil log . This little hand held pump is rated to 3 or 4k psi (we need to connect a working gauge tomorrow) The first truck we tried it on made a farting noise from the dummy plugs in the oil rails and shure as shit the orings were blown.
One thing we are unshure of is will the ipr hold this king of back pressure? With a guage and being able to close the ipr we are thinging we could use to differentiate between a leak in the piping and a bad HPOP.
We have tried using shop air for an air test but it never fails that we find all kind of "normally would not leak with oil" leaks once the oil is purged out
