WARNING
Gasoline system over pressurization can cause damage to both equipment and the ability to seal the
system. This can cause leaks, fire, damage, and death. Do not connect the generator gas line into
vehicle gas lines, as the system can starve or flood the generator, potentially causing damage. If
connecting to a vehicle gasoline tank, use a separate drawtube. Connect according to vehicle
recommendations and connect at a level higher than the vehicle so as to not run the vehicle out of
fuel during operations. Proper fuel line pressure should not exceed 1.5 psi under any circumstances.
This generator is intended for RVs that already have fuel lines ran to the compartment for the generator.
RVMP recommends that only trained and experienced installers extend or install any type of fuel line. For
fuel lines, the gasoline system should only use ¼ inch ID stainless or low carbon steel tubing (AISI
1008-1010) with double flared fittings to make any long connections. The tubing must allow 150 psi
operating pressure and have corrosion resistance equal to or better than hot-dipped zinc galvanized
steel.
When connecting to a gasoline tank, connect from the top, to prevent siphoning if a line is damaged.
Maximum fuel pump lift is 36 inches, therefore only install with less than 36 inches of lift from lowest fuel
level to the generator to ensure adequate pressure to draw fuel. Run fuel lines away from rough edges,
heated areas, and electrical lines/connections and properly secure to prevent vibration damage and
pinching of the lines.
Connect the fuel system to the generator with a ¼ inch barb fitting. When connecting hoses, use
only lubricants without soap such as WD40. Soap can be caught in the carburetor of the engine if used
and possibly cause in-operation. For connections at the generator or the fuel tank, use ¼ inch ID (SAE
30-R7) low permeation flexible hose with stainless steel ear clamps only. The hoses in the generator meet
US and California standards for gasoline evaporative emissions in that they are low permeation. If making
