<snip> I remember that there was a tiny bit of rubber on the <left injector> brass barb when I got the hose off for the frame brace installation.<snip>
You know that sage advice that the problem is always the last thing you touched? It has a great track record. However, there are exceptions. I was so fixated on the notion that the hose feeding the left injector had to be the leaker, that even after renewing that hose, I wasn’t considering leakage from anywhere else. At that point, a non-mechanically-inclined friend suggested tying strips of cloth at the hose ends to confirm the source. An embarrassingly good suggestion. Lo, as HalfFull mentioned, it was the hose running athwartship between the injectors, which I had not touched, that was intermittently leaking… at both ends. A little squeezing solved it.
I don’t share the distrust that some have expressed about the crimp hose clamps. My old VW bug used them without a problem and I found them on the fuel tank connections of my 35 yr old pickup truck. Granted, the injector system runs at considerably higher pressure than my examples. I do think that after a period of usage, re-crimping to compensate for some initial creep or set in the rubber tubing couldn’t hurt.
