The second issue about getting the fuel system to seal is worrying. Are you using the copper crush washers that were supplied? I think from memory they might be different sizes at each end of the filter but being away from home I cant verify that.

Thanks for posting as I find that sharing our thoughts helps create some knowledge around this relatively new engine. Of course, John Mc is pretty experienced with this engine and the fuel manifold setup so it could be worth an email direct to him to ask his views too.
Good advice, I will reach out to John and post on the Rotax Owners site.

I tried the particular filter with and without the washers with the same result. There were no washers used when the system was built, so I did not plan to use them. When I replaced the filter it sealed up fine without a washer. Guess it was just a bad one.
