Fuel Pump

This thread will explain the options if your fuel pump goes out. The EP-42S or equivalent makes a reliable and inexpensive alternative to the factory Yamaha pump.

Optional Fuel Pump Replacements - Forum thread

Fuel Pump Elimination - Many riders have also just eliminated it from the bike and everything still worked just fine. Some have adapted a Pingle fuel valve with a larger diameter outlet to allow for the fuel to flow a little better, but it is inconclusive as to whether it makes much difference. Removing the pump is simply a matter of removing it from the bike and running the fuel line directly from the tank to the filter, then to the carbs. Keep in mind there may be issues when your fuel level gets below 1/2 tank and you are going through corners as there may be some fuel starvation issues.

Here is a thread that explains the process. Thanks Steve (18apes)
