Earl's Performance LT Gen-V oil pressure gauge adapter fittings are needed when you remove the vacuum pump on the GM LT Gen-V 2014-and-up engines. When the vacuum pump is removed, it exposes two passages in the oil galley. These passages are metric straight threads—and they need to be plugged, or used for an oil pressure gauge or pressure sensor with the Holley EFI system (i.e., Avenger, Terminator X, HP, or Dominator). The adapters are available individually, in pairs (with a plug fitting), or in a kit that also includes an oil pressure sensor, adapter, and plug. Additional product details: * Vacuum pump delete adapters and plugs for GM LT Gen-V * Material: Stainless steel * Metric thread size in block: M12 x 1.75 straight thread with tapered seat * (1) adapter with female 1/8 in. NPT port * Ideal for engine swaps and racing applications that don't use the OEM vacuum pump
