Leaking Fuel Cap flange


Dennis Yeo

Recommended Posts

Speaking with Arian at Flight Design, there is a gasket that we can access after the Allen head screws are removed around the fuel cap.  He suggested Permatex No 2 on that gasket and that should fix the issue. (O rings are in good shape)

Anyone have suggestions on removing these Stainless Flush Allen Screws.  As you know stainless hardware is pretty soft, and when I try and turn the screws they feel like there are gong to strip out.  I am thinking there might be some sealant on the treads.

Any help would be much appreciated!

Just make sure you have a good well fitting bit that is fully seated in the fastener before applying torque for removal. You might try some heat right on the head of the fastener like from a soldering iron. Use a dab of the Rotax heat transfer paste to aid in heating it up. Just use caution since you are working close to fuel vapor.
