Working on a GM V8? This oil pressure gauge adapter kit is a handy tool for hooking up a pressure gauge or tester to your engine. It includes two adapters: a blue one (EN-47971) and a silver one (7219), both CNC machined from aluminum for durability. They fit a bunch of GM Generation 3, 4, and 5 V8 engines like the 4.8L, 5.3L, 5.7L, and 6.0L from around 1996 to 2006, and they also work on later Gen IV and V engines in vehicles like the Corvette, Camaro, Malibu, ATS, XLR-V, and STS-V. The adapter installs in place of the oil filter using an 11/16\ (17mm) socket, and it has dual ports so you can connect your tester from the bottom or the side. It's useful for checking oil pressure during diagnostics, maintenance, or even pre-lubing a new engine before starting it. A solid, well-made kit from EnRand that makes the job easier.
