| Looks like they tried to copy this manual, but failed. La-Z-Link That tester still doesn't give you a set pressure to test at. I don't think 40-45 psi is accurate. The correct method would seem to be to replace the right hand colored gauge with another gauge of at least 0-100 psi, if not higher. With the tool connected to the engine, adjust the regulator until the left gauge reads 100 psi, and read the right gauge.
