Not for engine leak down testing. Hose max pressure only 4 and half pounds
Not for engine leak down testing. Hose max pressure only 4 and half pounds. Hose stamped 4.500 which is very misleading making you think it can handle 4500 lb pressure. The hose very dangerously exploded under pressure. NOT FOR ENGINE CYLINDER PRESSURE CHECKING.

Too long
Imagine trying to thread this long hose into a plug hole when it’s close to the firewall or strut tower. You need to coil it up and make it as short as possible so you can spin it without cross threading. It’s too stiff to spin when extended out and bent around corners. Works fine when engine is out of car.

Air Valve Holder
Works like it should. Nice product if you need to hold valve up while engine head is still on.
