I’m currently rebuilding my XT and the previous owner said water pump was leaking but when i took off AC compressor i found out that the hose going INTO the water pump completely rotted away. Spoke to Subaru and they were able to give me part numbers but nobody has it, does anyone possible have a spare i can buy off them or i might have to find a fabricator to make me something like it. Found a website that has it but i never heard of it so I don’t want to resort to it unless i have to. Subaru part number is 14050AA001. All advice accepted

That's the standard EA82 water pipe. Discontinued. Any pipe from 85 to 94 should work the same. Those rot out frequently. Thus why they are NLA - sold out long ago along with oil pumps and all the other bits needed to keep the EA82 running.

Buy a used one. Don’t bother looking for aftermarket.  

Or bend some tube if that’s a good fit but it has a groove to hold an oring that seals into the water pump.  If that angle and seating isn’t right it’ll leak. 

Might be worth getting them electroplated ?

How bad is the leak? If it's just some pin holes, jb weld on the inside will work. If it's more you can braze/epoxy some larger of pipe over the hole.

 

Make sure you clean it really good before trying to patch it.

I've got a couple spare tubes, shoot me a PM.
