Hello I am selling a used OEM vacuum assist pump from a 2003 GMC Yukon with a 5.3 v8 engine. This is a good used pump and is ready to install on your truck, the pigtail is included with the pump as well.

Part number is 18049393

Every item I sell is carefully packaged with shrink wrap and bubble wrap to protect it in transit. I don’t cut corners on packaging because first impressions—and repeat business—matter.

Orders placed by 5:00 PM CST ship the next business day, and shipping is always free. You’ll get tracking quickly so you’re never left guessing.

Clear communication + fast shipping + accurate listings = buyers who come back.
