Installation
Series QP55-G Recreational Vehicle Generator
4- 2.4.1 FUEL TANK
Either the generator must share the vehicle
engine's fuel tank, or you must install a separate
fuel tank for the generator set. All fuel tanks
installed
on the vehicle must be constructed,
installed and restrained so they comply with applic­
able codes, standards and regulations.
If the generator is to share the vehicle engine's
tank, separate fuel pickup tubes are required for
the engine and the generator. Generac recommends
that you make the fuel pickup tube 2 to 3 inches
(51 to 76 mm) shorter than the vehicle engine's
pickup tube. This prevents the generator from
depleting the entire fuel supply during prolonged
generator operating periods.

CAUTION
A~
A D o not tee the generator fuel supply line into
the vehicle engine fuel supply line. If this is
done, the generator will be starved of fuel
when both engines are operating at the same
time. Also, while the vehicle engine is not run­
ning, generator operation may drain the vehi­
cle engine supply line, making it difficult to
start the vehicle engine.
♦ 2.4.2 GENERATOR FUEL SUPPLY LINE
2.4.2.1 Rigid Fuel Lines
Those lines used to supply fuel from a tank to the
generator must comply with applicable codes, stan­
dards and regulations. The following general rules
apply to rigid fuel lines:
• Rigid lines should be of annealed, seamless,
drawn aluminum or steel.
• Lines and fittings must comply with SAE J512F,
“Standard Automotive Fittings,” or with ANSI
B 126.26 (latest edition).
• Route the fuel line so that at least 2 inches (51
mm) of clearance is maintained between the line
and any exhaust system parts.
® Do not attach electrical wiring to fuel lines. Route
the wiring so it cannot come into contact with
any fuel line.
• Route fuel lines so if they leak, fuel does not drip
onto any electrical or exhaust system parts.
• Use nonferrous metal straps without sharp edges
to secure fuel lines.
2.4.2.2 Flexible Fuel Line
Use an approved flexible length of fuel hose
between the generator fuel inlet connection and
rigid fuel lines. This prevents breaking of the line
caused by vibration, shifting, settling or movement.
The following rules apply:
• The flexible hose must comply with SAE J30B,
“Standard for Fuel and Oil Hose.” It must be
approved for use with gasoline.
• The hose should be at least 6 inches (152 mm)
longer than is needed to prevent the hose from
rupturing if the generator shifts or settles.
2.5 EXHAUST SYSTEIVI
The generator exhaust system must be safely and
properly installed. Only approved mufflers and
other exhaust system parts must be used. A prop­
erly installed exhaust system must be vapor tight,
quiet and completely safe.
DANGER
The generator engine gives off DEADLY carbon
monoxide gas through its exhaust system. This
dangerous gas, if breathed in sufficient concen­
trations, can cause unconsciousness or even
death. Never operate the generator set with
the vehicle inside any garage or other enclosed
area. DO NOT OPERATE THE GENERATOR IF THE
EXHAUST SYSTEM IS LEAKING OR HAS BEEN
DAMAGED. SYMPTOMS OF CARBON MONOX­
IDE POISONING ARE (a) inability to think coher­
ently; (b) vomiting; (c) twitching muscles; (d)
throbbing temples; (e) dizziness; (f) headaches;
(g) weakness; and (h) sleepiness. IF YOU FEEL
ANY OF THESE SYMPTOMS, MOVE INTO FRESH
AIR IMMEDIATELY. IF SYMPTOMS PERSIST. GET
MEDICAL HELP. Do not operate the generator
until its exhaust system has been inspected and
properly repaired.
------- M CAUTION M. ---------------
Never tee the generator engine exhaust pipe
into the vehicle engine exhaust piping. This
causes excessive back pressure on the genera­
tor engine. Also, water from one engine can
damage the other engine.
