2. Determine fuel requirements at full load. See the Model Specifications section
to determine the fuel flow requirements.
3. Determine equivalent length of fuel line fittings required. See the NFPA Pipe
Fittings table in the Fuel Line Selection appendix to determine the equivalent
lengths for elbows, tees, and valves. Add this length to fuel line length to
determine total equivalent length.
4. Determine required fuel line size at full load. See the Fuel Line Selection
appendix to determine the fuel line size.
To calculate the minimum pipe size:
1. Make a list of all the fittings and valves in a proposed system and add their
equivalent lengths.
2. Add all lengths of straight pipe to arrive at a total equivalent length to the
fittings/valves total.
3. Choose the applicable table based on the fuel system and fuel line material.
4. Obtain the maximum fuel requirements for the specific generator set from the
Model Specifications section.
5. Refer to the fuel line sizing charts in the Fuel Line Selection appendix. Locate
the equivalent length of pipe (or next larger equivalent length) in the left hand
column. Move across the row to where the maximum capacity number is as
large or larger than the maximum fuel consumption (or next larger). At the top
of that column is the minimum nominal pipe size or tubing size required for the
system as designed.
Installing Fuel Lines
The basic components required for fuel line installation are as follows:
• Flexible connection
• Fuel line
• Shutoff valve
• Fuel supply
To install the fuel lines:
1. Connect a flexible fuel line to the fuel connection ports on the generator set.
2. Connect the opposite end of the flexible fuel line to the fuel source line near the
shutoff valve.
NOTICE
A shutoff valve is recommended and often required by local and state codes.
Testing the Fuel System for Leaks
After assembly and before initial operation, all of the fuel system components must
be tested and proven free of any leaks.
