I can't seem to find any diaphragms to overhaul my fuel pump. Can build an airplane, overhaul an engine, wire up avionics but can't find any diaphragms for my lycoming fuel pump P/N LW15473.

Any ideas folks?

Never seen them (gaskets/parts) for sale, nor overhauled pumps lately. Fuel pumps are considered not a field overhauled unit.

I personally wouldn't take any risks in this area...

Look on ebay. There are a couple sellers with rebuild kits for AC pumps. Ethanol compatible. Easy to do. Don't let the nambies stop you.

I just did a search as you suggested. I see the seller mentions that these kits contain unleaded and ethanol resistant parts. Yet he mentions that the diaphragms are made of Neoprene rubber, which isn't the recommended material for unleaded gasoline or gasoline containing ethanol.
Just for information's sake, were our Lycoming AC fuel pumps also used on a specific make or model of automobile?

Went a head and purchased a new fuel pump. Thanks all for your responses.
