OK, I know now. The little spouts on each injector are the "barbs".

Well, come to find out, it IS odd that an injector should be leaking from the middle of the injector body.

In fact, those lines were looking a little old, and yes, I found that it was a leaky cloth line, and NOT a bad injector (thanks,gsxr!)

What's the best way to plug off the last injector in the series? Currently, I have a little bit of cloth hose coming off the last barb that is crudely blocked off with a bolt or something. It doesn't look like a factory fix. Any proper way of blocking the final barb, or is it supposed to lead somewhere else.

Any thoughts?
