Auxiliary fuel pumps

This is interesting. In the last 2 years I've purchased 4 of the 4140-00-15 pumps and paid less than 700.00 exchange for each of them directly from Cessna.

I just spoke to the local Cessna dealer and gave them the part #1426033-3 (4140-00-15) for pricing. They told me this pump is no longer available and the part number is superseded to 18000B. The pump they sell is a new Rapco pump, no exchange required.

If Cessna is supplying Weldon pumps as a replacement for the Dukes pumps then no STC is required.

If I was going to buy one of these pumps I would do a bit more research to confirm what I have just stated.
