California Proposition 65 Warning

All vacuum slides are test fitted and inspected by CVP prior to shipping to meet specifications and are verified functional for their intended use. We personally inspect the diaphragm before shipping to be free of any cuts or damage.

Manufacturer warranties the slide portion only (metal casting) against manufacturing defects for 90 days from purchase date. The rubber diaphragm portion is not warrantied after receipt and/or installation since the manufacturer or seller has no control over any possible adverse conditions that may occur. It should be noted that the rubber diaphragm is very delicate, and any mishandling including pinching the diaphragm with the cover during installation will cut or tear the material and is not covered by any warranty.

For warranty issues please contact CV Performance in writing. If a warranty claim concerns any sort of defect with the cast slide portion of the assembly the seller will issue a RMA number for the original customer to return the slide for inspection. An RMA does not guarantee acceptance of return or exchange. Upon inspection if the item is determined to be defective the seller shall provide a replacement in exchange only. This warranty does not provide for a refund or compensation in any manner. Warranty does not cover any time, labor, shipping, or any other claim of loss incurred by any party whatsoever.

CV Performance reserves the right to deny a warranty claim due to factors including but not limited to; abuse or misuse, exposure to solvent or chemical, damage from overheating or backfire, any damage caused by the customer's equipment or carburetor itself, damage or improper handling by installer, damage caused to the product from any other product or device, or handling by any third party shop or installer.

CV Performance is not liable for any damages or loss related to this or any product.
