Re: Help - Water / Fuel Drain valve leaking ??
Before you replace them, you may want to try the following procedure. I had trouble with mine on two different occasions and replaced O-rings both times. It has since leaked temporarily right after flushing and replacing fuel filter.
Now, when finished with filter, I simply start the engine. While it is running, I do a series of 1-2 second blasts for 6-8 times quickly closing the yellow valve all the way each time. This apparently cleans the Oring area sufficiently for no more leaks. I have done this successfully the last two filter changes with no leaks.
As for replacing the small Orings, it is pain in the a** if you have big hands. Very difficult to manipulate the small 1/4" wratchet with Torx.
