3.8.4.3 Propane Vapor Fuel Supply Line Size and Pressure
Fuel line size depends on the amount of fuel needed to run the generator set at full load at the
distance the fuel must be moved.
• See the Generator Set Specifications Table for fuel system specifications, such as the
amount of propane vapor at certain loads.
The following figure shows a typical Propane vapor installation and the table below lists fuel
capacity for given distances and pipe size.
Size the fuel line so that the Propane vapor pressure drops no more than 1.5 inches WC from
no load to full load.
NOTICE
For Spec A and Canadian GSBB Spec B, make sure the fuel supply pressure at the inlet of the
generator fuel regulator (at service port) is set between 7–11 in. WC for all operating loads (no
load to full load).
For US GSBB Spec B and Canadian GSBC Spec B, make sure the fuel supply pressure at the
inlet of the generator fuel regulator (at service port) is set between 12–14 in. WC for all operating
loads (no load to full load).
