What are the fuel system requirements for the ULPower engine?

The fuel system installation for the ULPower engine differs from carburettor engines. Whereas a carburettor engine will usually have only one, small diameter fuel line from the fuel tank(s) to the carburettor, the ULPower engine has a closed loop fuel circuit. This means that the fuel line departs from a fuel reservoir to the electric fuel pump which then sends fuel to each fuel injector block on the engine, and the excess fuel is then returned from the engine to the same reservoir where the fuel is drawn from. This is the same setup as in any fuel injected automotive engine.

In the drawings below you can find some basic info but since having a correct fuel system is essential for your engine and your safety , we recommend to consult our installation manual for more detailed information.
