Make sure you get glow plug fitting, the injector ones aren't accurate

Harbor freight ague are junk, the fitting can work with some cutting but the gauge itself is junk. Bought a different one online that worked a few tries and then stopped... I think the sealing oring popped and decompressing hurt it

Looks like cheap ain't the best route sorry
