It's not a structural material, so it wouldn't add strength. I suppose it would depend on how worn the threads are. If the fitting doesn't stay put on its own without some kind of goop, I might recommend drilling and tapping to the next larger size. Another possibility is to glue on a fiberglass or aluminum doubler plate drilled and tapped for your fitting. I'd use fiberglass resin for the fiberglass doubler. However, if you decided on an aluminum doubler plate, I'd use 3M structural adhesive. It so happens I've used this structural adhesive to attach aluminum fuel-gauge bosses to fiberglass tanks and it's worked well. Either way, I don't see any reason a doubler plate wouldn't work.

There has been an bad accident here (just after take-off) because of a fuel pump with too high pressure. This may block the floaters in the carburettors.

From: "Roger Lee" Hi Guys, I talked to Rotax today and you early engine owners are absolutely right that back in the 90's the 912 engine did not have that cover. They did however say that you need one on there now. The cover is $75. -------- Roger Lee Tucson, Az.

I guess the next size bigger would be the best way. The threads stilll hold and are tight. I used Permatex non hardening. Filled the tank today and no leaks. guess I'm OK. Just makes you wonder when the stuff is still barely tacky after a day to set up.

I am printing out the manometer info page. I found there was a piece of surgical tubing that connected the pitot to the black plastic tube in the wing that rotted out causing a major leak. It was a bear to replace even with my small hands, but at least there was an access plate at that point. I will now see how accurate the ASI readings are. I did do the rollup of a surgical tube on the pitot tube that held pressure on the ASI.

Mud Dobers got into the pitot tube of which I thought I had removed all the dibris only to hav e some of the loose sand which they use flow into the asi and then plug the screne at the exit port of the indicator. I removed the indicator and all tubing conectors on the back side and was able to see the pluged screan. Ho lding the unit with the ports down I carefully brushed the screan with a so ft fine wire probe and watched the dirt fall out. This worked for me and ha s been fine ever since. Your indicator may be different and I don' know why there is a screan at the exit port only except for possibly some backpress ure to make it work right. I hope this will help you out too.
