IO-390 intake pipe ring seals

[dpansier]

Ordered new O ring type intake seals for my 390, part number 72711.
The width of seals I received were a very small diameter, the old seals are much larger in width, aprox .250 diameter or so.

Anyone know the correct part number for the larger width seals for the 390?

77569 for the classic horizontal intake sump.

72711 for the C/D style intake manifold (separate from the sump) found on a -199.

Thanks Dan, just what I was looking for.

If someone needs a set of 4 new Lycoming P/N 72711 let me know, make a $20 donation to Doug at VAF and I will pickup the postage and get then out.

I have the opposite problem, I got the thicker seals and need the thinner diameter ones. Would be happy to send you mine if you send me yours.

Send me a PM is your interested.
