Earl's Performance GM LT Gen-V Oil Pressure Gauge Adapter Kit

Earl's Performance GM LT Gen-V Oil Pressure Gauge Adapter Kits are purpose-built solutions for builders and engine swap enthusiasts working with GM LT Gen-V platforms from 2014 and newer. When the factory vacuum pump is deleted, two oil galley passages with metric straight threads are exposed and must be properly addressed — these kits deliver the precision hardware needed to seal, adapt, or monitor oil pressure with complete confidence.

This product line spans multiple configurations to cover every build scenario. Whether you need to simply plug unused ports, add an aftermarket oil pressure gauge connection, or integrate a full electronic pressure sensor with a Holley EFI system, there is an option engineered specifically for your application.

Key Features:

• Designed for GM LT Gen-V engines (2014 and newer) following vacuum pump deletion
• Precision metric straight thread construction with tapered seat design ensures a reliable, leak-free seal against exposed oil galley passages
• Stainless steel construction throughout for long-term durability and corrosion resistance
• Enables connection of aftermarket oil pressure gauges and electronic pressure sensors to previously inaccessible oil galley ports
• Compatible with Holley EFI systems, including Avenger, Terminator X, HP, and Dominator
• Available in multiple configurations — plug-only, adapter-only, adapter and plug combinations, or complete sensor kits with pigtail wiring harness
• Ideal for engine swaps, performance builds, and racing applications where the OEM vacuum pump is not retained
