This remanufactured pump provides a cost-effective replacement solution for failed or worn CP4 pumps.

Proper installation and fuel system cleanliness are critical to ensure long-term reliability and prevent contamination-related failures.

Pretty badass. Company is legit. Spoke with customer service before I placed my order. Good service! Literally the cheapest price on the Internet.

Great price and easy checkout.

well made website would give 5 stars if i could confirm fast shipping.

After having trouble completing the payment process through Amazon, I was able to complete my payment information directly on the Autoplicty website and submit the order quickly. The process was easy and fast. They had the best overall price (item plus shipping) I could find on the net. The item was shipped promptly and arrived in great condition. A quality merchant all the way around.
