Safety Regulations for Compressed Natural Gas and Liquefied Petroleum Gas Powered Vehicles: Components

WARNING: This page is about a different car, the 2017 Chevrolet Spark. However, it is still accessible from the selected car via links, so may be relevant.

Because type-approved parts are assigned to the vehicle by registration number, gas system parts that require registration must be documented in the vehicle's Check Booklet when they are replaced. (see chapter "Registration" in this document).
Gas system components such as (e.g.) the pressure reducing valve, are sensitive to impact. The installation of gas system components which have fallen onto the ground is prohibited.
Strict observance of the use of materials and additives (such as approved assembly pastes) is required for certain operations in the Service Instructions.
Only those replacement parts approved and released for the relevant vehicle may be used in the gas system.
Other parts may not be used, as these are not type approved and result in the cancellation of the type approval.
The connections of gas system components must be sealed immediately after removal using tight-sealing closure caps.
In warranty cases, returned components which have not been sealed cannot be accepted.
Remove new parts from their packaging immediately prior to installation and check visually.
