Warnings
The AltFuel Green Conversion kit is engineered for use on only engines that are in excellent running
order. Due to the characteristics of propane vapor fuel engines that may run ok on gasoline but
have underlying problems will not run as well on propane. Engines that have lowered compression
due to wear will run near full power on gasoline but won’t be able to make full power on propane
vapor due to the compression loss.
AltFuel does not recommend the conversion of engines used in a commercial setting that have over
500 hours unless the engines have been excellently maintained and have near factory compression.
The AltFuel Green Conversion kit will not fix problems that already exist in an engine.
If your engine is already consuming oil, or more than 1 ounce per hour run time, it needs to be
replaced or repaired. While LPG extends oil change time it still must be checked regularly and
before each use.
AltFuel cannot guarantee the performance or end result of an improperly installed kit.
The AltFuel Green Conversion Kit runs on vapor propane and can only be fueled by a vapor service
cylinder. Use of a liquid service cylinder will permanently damage the Regulator system.
If your engine is 10 Hp or higher, the regulator system must be mounted vertically. If your engine is
less than 10 Hp the regulator system must be mounted vertically.
If your engine is less than 10 horsepower it must be mounted horizontally.
