OK, now this bike is really pissing me off

So, when I replaced the last fuel pressure regulator it blew after half a mile.  But I had picked up two of the same part, just in case.  Two is one and one is none, right?

So yesterday I go out to do the switcheroo, and when I open the package IT'S THE WRONG FUCKING PART.  It's a regulator, but it doesn't go to my bike.  I don't know what machine it's supposed to go on, but mine ain't it.

So my bike is still a 750 pound pile of crap on two wheels.  It'll take about two weeks to get my part here.  Once I get it, I'm putting it on the bike and trading it in.  I'm done with not having a reliable machine.
