LS Engine Swap M16 1.5 Adapter to 1/8 NPT Mechanical Oil Pressure Sensor LS1 LSX LS3 Gauge 551172 for GMC Chevy Oil Pressure Switch

My car is equipped with a Holley terminator system. This adaptor allowed me to install a standard pressure transducer in the oil pressure port of my 5. 3 to allow me to connect the engine harness It worked flawlessly!.

2004's works 3L chevy. On my 2004 suburban 5, I used it to connect an oil pressure gauge. 3L. I wanted to make sure my gauge cluster was correct, and this fits perfectly in the spot where the oil pressure sensor should be. It met my needs perfectly.

However, you'll need a 25mm wrench to use it because they went with that size rather than the much more common 24mm - My wrench and socket set both come to a halt at 24mm. Also, they didn't put much effort into finishing the adapter, so the edges are very sharp and painful to tighten by hand.

This adaptor was used to connect a temporary mechanical gauge to the factory cluster in order to troubleshoot a low oil pressure reading. The fitting sizes are correct, and the adaptor fits the factory sensor location on the engine, allowing the mechanical gauge line to be installed.

Fits a 5. 3 liters are perfect, and the finish is nice. For what it is, it is excessively expensive.

This is ideal for manually inspecting the LS motor.

For a Chinese product, this adapter is of reasonable quality. The included aluminum seal washer may function properly, but it is extremely thin. I finally settled on an M16 copper drain plug seal, which was the perfect size and performed admirably.
