In stockFuel Regulator

Overview

Generac part 0J9045 is the genuine Generac pressure stabilizer regulator assembly (Generac description: "Assy Pressure Stabilizer Reg"). It combines the gaseous fuel regulator with a plenum stabilizer tank, so the engine receives fuel at a steady, consistent pressure. It is a new, factory Generac assembly supplied under Generac's own part number.

Key features

  • Complete assembly: regulator body, black plenum/stabilizer tank, flanged outlet tube and fuel solenoid, as shown in the photos.
  • Steady fuel pressure: the stabilizer tank smooths out pressure swings between the regulator and the engine.
  • Genuine Generac part: new OEM component, identified on the tank label as 0J9045.

Fits

  • Generators: Generac generators whose parts list calls for 0J9045. Generac uses several different stabilizer regulator assemblies (for example 0F9078, 0G7581, 0J8312 and 0K3964), so match the exact number from your parts manual.
  • Typical equipment: Generac gaseous-fuel (natural gas / LP) generators.
  • Confirm fitment: send us the model and serial number from your generator's data label, or the number on your old assembly, and our team will confirm it before you order.
