Tom, I installed your fuel line system last year and enjoy its strengths! Do you offer the fuel return fitting with larger orifice? Iím experiencing spiking fuel pressure indications in the dynon/green-yellow band with aux on and off in various phases of operation. Could this cause a slightly rich fuel mixture?

Thank you!
Doug

HI Doug. right now we dont, BUT the good part of our fitting is that you may drill the orifice to a slightly larger size if you wish.

Tom, thank you for that ultra thin bit. Will it fit in an electric hand drill? I donít have a press. I guess I could go to a machine shop. From which end do I drill?

Doug....

Good afternoon. You need an air drill to drill it out as the drill bit is really tiny.

I drilled one out for you today and if you send me an email I will send you the new restrictor with a larger hole. The new restrictor fitting is drilled out to .020-.021 which is slightly larger than the .015 that is specified in the Rotax manual. However, it matches the orifice size that is actually being shipped by Rotax. Their manual and actual restrictor orifice sizes differ. We have tested both orifice sizes and have noticed no appreciable difference between them.

Have a great week and take care,
Steve
