All warranties implied by State and Provincial Law, including implied warranties of merchantability and fitness for a particular purpose, are expressly limited to the duration of the limited warranty set forth above. In addition, this warranty excludes Diesel Management of being liable for incidental or consequential damages in connection with the use of Diesel Management products. This warranty gives the purchaser specific legal rights, and you may also have other rights that vary regionally or nationally.
