I have this pitts style Bisson muffler.

The pressure fitting points at the fire wall. I can install the fuel tubing vent line, but it has a pretty tight turn and might rub against the firewall. Can someone please tell me where I can get a 90 degree fitting to replace the straight one that comes with the muffler?
Thanks for your help.
