Each Billet cover comes with a high pressure plug rated for pressures above 150 PSI at 350 F steam pressure. Oil Pressure Gauge is only recommended to be used for diagnostics (not IP67 rated). The acces-port should not be used as a permanent under-hood-gauge solution.

Gauge Install Instructions for Diagnostic Use (sold separately)

Second, install the oil pressure gauge (Sold Separately) with thread sealant (automotive grade) as directed and twist onto billet cap tightening up to two turns from finger tight. Check for leaks once engine is up to temperature and sealant has been allowed to set (see sealant manufacturer’s directions). Removal process is opposite of install.

Over-tightening of O-Ring Boss plug on port-access may damage the anodized housing and/or O-ring. Plug needs to seal at a maximum 5 lbs ft with fresh thread sealant.
