OK hardware experts --- here is a challenge.

 

Legacy construction manual page 26-26 specifies bulkhead fitting 2240-6-8S for the gascolator through the firewall.  3/8" male NPT on the engine side, with 37 degree flare inside the firewall.  The only problem with this fitting is that it is difficult to run an aluminum tube directly into the fitting at 90 degrees (without making a relatively large 90 degree bend in the tubing).  And I don't know of a 90 degree AN fitting that will adapt from flare to NPT.  One solution might be to use flexible SS/teflon hose with a 90 degree fitting, but I would prefer to use aluminum tubing.

 

What I think I need is a steel bulkhead fitting with 3/8" NPT on both ends.  Can anybody give me a part number and source for such a fitting?

 

Thanks in advance for any light you can shed on this issue.
