    • In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.
    • We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction).
    • Annual membership also comes with two BiplaneForum.com decals.

Must be my week for questions - - - Since 1971 I have never found the need for using an AN reducer, they came in yesterdays mail. I am reducing 3/8" to 1/8". I screwed the reducer on to the AN838 bulkhead fitting and thought - no "O" ring, no flared tube, no sleeve, no way this isn't going to leak.
Am I suppose to believe that butting two 37 degree tapers together is going to be fuel tight ? And, when the reducer is almost tight it contacts the bulkhead nut so I am not sure how tight I will be able to get it anyway. What am I missing - - this time :(
Thank you - again

Think I will check u-tube whilst I await replies

Last week someone said, "lets wait until we get to know you better before we decide if your questions are stupid or not."

I am afraid to ask . . . .
