Which Weldon boost pump

[Martin S.]

Hello gents,

Question on the Weldon boost pumps, trying to find out which one I would need for my M20J (24-0520). Aircraftspruce lists the 18020-A and also the A8163-A for my serial number. If it matters, I had a dukes 1499-00-19 installed, engine is an A3b6d.

The only IPC for an M20J I have says Dukes 1499-00-19/19A is replaced with Weldon A8163-A, but you need retrofit kit #940018 to do the swap.  I'm sure someone else more knowledgeable will be along shortly.  Usually, people have these rebuilt.

Thanks - I didn’t know it requires modification. Did a quick search, seems like the mod takes quite some labor. This will definitely make me reconsider whether I shouldn’t simply overhaul my dukes.

Does any of the European pilots know whether there’s a company that does dukes pump overhaul on this side of the Atlantic? Otherwise I guess I’ll contact Aeromotors LLC.

Aeromotors is the name that comes up most often.  I suspect the shipping is brutal.

Does anybody now which fittings to use for the Dukes pump drain nipple? The IPC mentions B-1-ON-2. Where can these be found and/or is there another name for these?

See the last page. The fitting is a Dukes part 2140-93
