We are a manufacturing company that builds CNG Fuel systems for Class 8 trucks. The chassis comes with an engine designed by Cummins to accept CNG fuel in place of diesel.
Our part of the vehicle build is to build and install the fuel cell and components necessary to deliver the fuel to the engine.
We do not fall under the chassis or engine warranty. Therefore, would we fall simply under 9001 or do we have enough involvement in the vehicle design and build to need 16949?
