Generac 0J8312 Fuel Regulator Assembly With Plenum Stabilizer Tank. The black tanks (plenum) on these fuel regulators should be inspected during regular maintenance (or more if you live in a salty or harsh environment) for rusting and should be replaced if any signs of rust appear as you could have a fuel leak.
Generac replacement parts will also usually fit the following Generac branded generators: Honeywell, Guardian, Siemens, Carrier, Watchdog, Centurion, & Bryant.
