Review on IVARKEY IPR Valve Air Test Fitting Tool & Oil Rail Adapters Leak Test Kit: Ideal for Testing Ford 6.0L Powerstroke Diesel Engine (Fuel Rail) by Richard Counts

Item did not match the test item thread, did not match the engine part thread because it got tangled when inserting the item manually, and yet you don't dare to tighten the key because the replacement of the engine part would be very expensive if the threads were damaged rendering the engine part unusable as the pressure from the HPOP is very high.
