6.7Natural or LP Gas Fuel Systems

Natural and LP (liquified petroleum) gas fuel systems should be designed and installed in accordance with the requirements of NFPA 54, National Fuel Gas Code, and all applicable local codes. Various types of gas fuel systems are available as follows:

DLP Gas Vapor (Figure 6-5 and Figure 6-6)

DLP Gas-Liquid Withdrawal (Figure 6-7)

DCombination Natural Gas and LP Gas (Figure 6-8 and Figure 6-9)

DNatural Gas (Figure 6-10)

DCombination LP Gas or Natural Gas and Gasoline (Figure 6-11)

The engine-mounted components of all these systems are similar and usually include a carburetor, secondary gas regulator, electric gas fuel solenoid shutoff valve, and flexible fuel connector.
