I would go to a local Napa and explain you're problem. He may be able to find one for you or better yet, he'll show you the wall of hoses hanging in the back and you can sort through them until you find what you need. When I built my 34 Ford 3 window coupe a few years back, that's exactly what I did when it came to formed radiator hoses that I needed. Plus, it was also how I found a few other things like belts and such that I could only get by searching through a pile of parts and picking out what I needed. I do remember getting a 90 degree 1/2" formed rubber hose for the power brake booster that was from a Ford Explorer or something. I'm pretty sure I remember the guy saying it was fuel injector hose. And that was at Napa. Good luck. Hope that helps.

Cheers
