It is often very simple things that will stop your pride & joy. This years monsoon season is well underway, and we are fielding many calls due to water contaminated fuel. We have completed two jobs this week where water contaminated fuel has occurred due to a failed o-ring on the fuel cap. In both cases, costly repairs could have been avoided by fitting a replacement fuel cap. If you notice surface rust on your fuel filler neck there is a good chance you are taking on water.
