There's a steel piston on the bottom of the IP that wears the casing wall and allows fuel to bypass. I took all of my injectors and the pump into a local shop to have them inspected and tested and every one of the injectors failed the test, one even having a broken spring inside which allowed the fuel to constantly flow through. I opted to have them rebuilt vice replaced since I know the local business will stand by their work 110% unlike many vendors online. I had the pump completely rebuilt as well once it was demonstrated to be a prime example of the common piston-wearing-the-casing issue. The fix so I'm told is to ream the housing and install a larger dia piston.
