What is it? This is a regulator from GM, factory part number 19162021. It is catalogued under Valves & Regulators > Regulators & Adjusters.
Anything to check first? Keeping the old part until the new one is fitted and checked is the simplest way to avoid a second order. Match this against the part you are taking off rather than against a photo. If the number is unreadable, send us the VIN and we will confirm it.
What else matters? Torque figures belong to the fastener and the joint rather than to the part, so the factory procedure is the reference rather than a general rule.
How fast does it ship? Leaves our US warehouse in one to two business days, and shipping is free over $59.
