om603 fuel thermostat
om603 fuel thermostat
so mine has leaked for awhile and today, it became bad. So i bypassed the thermostat while retaining the heating loop so the fuel is still being heated. How important is retaining the fuel thermostat. What can i expect by not replacing the o-rings and putting it back?
i´ve read somewhere dont remember where, the fuel heat exchanger thermostat is set to 24ºC, unless u are in a very cold place u should not need it. after a wille even witout fuel heater all fuel tank will be hot, due to the fact that fuel is running inside IP wich is heated by engine oil. the return line to the tank will cool a bit acting as heat dispenser, heating continously will result in heating all the fuel tank faster and too high since it does not have the desired cooling wich the return line provide.
the main idea behind this setup is to have the fuel at room temp as fast as possible and mantain it.
so fix it and u be fine.
