Oil Pressure Adapter

Product Info

The factory 4200 oil pressure is a fraud. Yes, for some reason GM decided to use a switch instead of a sensor. The factory GMT360 and GMT355 guage in the dash is completely made up by the ECU based on engine RPM, and the only time it shows a real number is if it's too low, which could be too late.

This is a special fitting (designed by me for the Atlas engines and not a re-purposed LS design) allows an aftermarket gauge or pressure adapter to be added to the un-used port on the front of the block's oil filter casting. This is a higher quality part that's also less expensive than anything you will get on amazon, and you're supporting me instead of Mr. Bezos. 

Works with any Atlas engine: 4, 5 or 6. Anodized 6061-T6 Aluminum. The M16x1.5 threads are the exact length as the OEM plug, and the internal thread is common 1/8" NPT to fit a wide variety of sensors, hoses or gauge adapters.

Please note: This fitting is NOT long enough to fit the oil galley ports on the side of the block! Do not attempt to use it there for oil feeding!
