I didn't think to check the LWS for a smaller barb that would work with this regulator! I guess I just assumed it would be some one-off imported thing! They would have been closed by the time I'd have gotten there anyway, but maybe this weekend I'll swing by there and check it out. While what I have is working (I used 3 feet of 200psi 1/4" id fuel line), I am a bit concerned that over time, the end with the smaller barb could loosen up and start leaking. The QR barb itself offered next to no resistance when I inserted it into that hose...if I'd gently swung the hose around, I'm sure it would have fallen out. So if I can get a replacement barb for the regulator that matches the one on the quick release fitting, that's what I'm going to do.

I'm still trying to figure out how to identify if the foot pedal that I got is the one I was supposed to get. Does anyone know of a way to identify which one I have? The one I have is totally smooth and flat on top...there is no raised lip to catch your heel.
