Hi guys! I have a 90 CRX HF and an 87 Prelude Si. Both 100% stock owned by old folks, the usual. Daily is a 2017 Civic EX. Im an engineer, usually. The company I work for is small so I also double as plant/field maintenance. I just like Honda's for the simplicity, really. Reliability as well. I have previously owned 3 WRXs, with less than impressing results, so back to Honda I went!

I am having an issue though, with the fuel line/rail on my Prelude. Took the fuel rail off to remove the injectors. Removed the larger cap type bolt over the banjo connection on the passenger side of the rail and it fell off and disappeared straight to oblivion. Been looking for days. Seeing as how I can't attach my fuel hose to my rail, this is a big problem. I don't mean to be cheap but can I just get a metric acorn nut? Does it have to be capped or can I run it home with a regular nut? What's the thread size?

I have no scrap yards near me otherwise I'd try to pull something off some other Honda.

Any help would be appreciated, guys!
