I have had fuel injected cars for over 30 years. I have never seen an issue with the fuel injection systems. Some of those cars were high mileage and some I kept for a long period of time. We have been using 10% ethanol gas in our cars for some time. If you plan on not using an EFI golf cart for some period of time use fuel stabilizer or put in a tank of non-ethanol gas before leaving. I suspect the move to a fuel injection system by Yamaha EFI cart was for improved reliability, less maintenance, and improved gas mileage.

Over time injectors become clogged due to hydrocarbons, sediment and other elements in the fuel. Internal components rust due to the presence of water in the fuel. Water gets into the fuel due to the fact that the Ethanol in the fuel is hygroscopic.

Injectors also get gummed up with varnish and gunk formed when fuel is left in the tank for long periods of time.
