Posted this to the Skywagon group and haven’t gotten a response:


I'm looking for a part I can't find in the IPC. Fuel drain (sump -- under the wing thing) for 1981 A185F, s/n 18504181. Eyeballing the Spruce catalog, it looks like maybe "Cessna Drain Valve S2020-2." Does that seem right?

IPC Fig 10, Find #1 for your s/n effectivity shows S2020-2, which crosses to SAF-AIR p/n I believe.

Thanks. I’ll take a look at that.

P/N CCA-2900 are the ones on the bottom of the wing tanks that I used on my A185E. They are on the McFarlane website. https://www.mcfarlaneaviation.com/produ ... /CCA-2900/

FWIW my 53 C180 uses SAF-AIR p/n CAV-180 quick drains at the tanks,
and CAV-110's at the belly & gascolator.
