PERSONAL DANGER - Do not use galvanized pipe in fuel line
runs. The galvanized coating can become eroded and fl ake off,
causing possible obstructions in the regulator or fuel valve. The
results could range from inoperative engine start to hazardous
fuel leaks.
Size of pipe normally required for generators operating on NG/
LP:
UP TO
25 FEET*
OVER
25 FEET
GR150P4
2.0” pipe
NOT
RECOMMENDED**
* Allow an additional 3 feet for each standard elbow.
Do not use ‘street ells’ (restrictive).
** USE THE TWO REGULATOR SYSTEM SHOWN BELOW.
**** CAUTION ****
EQUIPMENT DAMAGE - Be careful when sealing gas line joints.
Excessive sealing compound can be drawn into the solenoid,
regulator or carburetor causing an engine malfunction.
FUEL PRESSURE (vapor system)
Correct fuel pressure cannot be stressed enough. The most
common cause for inoperative systems is an inadequate or
incorrect fuel pressure. Power and performance of the engine
is in direct relation to the correctness of the fuel system. Shown
below is a diagram of a typical L.P. or N.G. installation.
Reference numbers 1 through 3 in the diagrams below are
system parts supplied by customer.
Reference number 4 is the engine generator set.
Below is a table of the fuel pressure reading at each reference in
the system.
