Hi, so I'm in the process of getting my recently acquired 1971 1800E reliably roadworthy. After seeing how rusty the old gas tank was I decided to just get a new reproduction tank. After contacting several people (VP autoparts, Classic Volvo Restorations etc), it seems like nobody has the tank elbow barb fitting in stock and they aren't expecting them soon. I have this tank https://classicvolvorestoration.com/volvo-1800-fuel-exhaust-system-parts-/20318-fuel-tank-volvo-1800-ees-1970-73.html . Does anyone know the size of the elbow threads that go into the tank and the output size of the barb fitting? It looks like at least 1/2 inch NPT threads, but I can't tell for sure and would I be looking for a 5/16 barb or 3/8? I'm trying to find something on Summit or something that I can substitute so I can get my car back on the road. Thanks!
