Scott, I faced the same problem back in early days. I ended up threading the inside. I put a borrowed tampax down the tube coated with grease and carefully push the string in as well. Tapped the tube then reached inside the tube with a needle nose and grabbed the string and carefully pulled it out with all the metal shavings from the tapping operation.
I was too chicken to try and pull the tube out.

Subject: [FlyRotary] Heater Outlet Threaded?
Hello Everyone...
The attached photos depict the heater outlet. I had originally hoped
to just use regular heater hose and barbed fittings. However, as my
setup has come together there are just too many things trying to make too
many turns. What I really needed was a 5/8" 45 degree or 90 degree
barbed fitting. I tried my usual spot of fittingsandadapters.com , but no
luck. Thus, I am considering tearing the fitting out of the housing
and replacing it with an AN fitting which I can use with socketless hose
or something of the like.
It looks like the fitting is not pressed into the housing, but rather
screwed in( I have been unsuccessful at turning it even using heat and
cold ).
Is it really screwed into the housing? If so, would it be to much to
hope for it to be 1/2"npt?
Any ideas on how to salvage the simple barbed on hose setup?
Any info, thoughts, and references are appreciated....
Thx...
-Scott
