              Subpart A_Determining How to Follow This Part
 
Sec. 1051.25  What requirements apply when installing certified engines 
in recreational vehicles?

    (a) If you manufacture recreational vehicles with engines certified 
under Sec. 1051.20, you need not also certify the vehicle under this 
part. The vehicle must nevertheless meet emission standards with the 
engine installed.

    (b) You must follow the engine manufacturer's emission-related 
installation instructions, as described in Sec. 1051.135 and 40 CFR 
1068.105. For example, you must use a fuel system that meets the 
permeation requirements of this part, consistent with the engine 
manufacturer's instructions.
    (c) If you install the engine in a way that makes the engine's 
emission control information label hard to read during normal engine 
maintenance, you must place a duplicate label on the vehicle, as 
described in 40 CFR 1068.105.
