so, performance debate aside, I need some help.
It's been a while since I've swapped, but when I found out I had a bad injector, I bought a set of reds off ebay. They're supposed to be the same flow as brown, so I thought "no big deal".
now, somewhere along the line, I have a small fuel leak. I'm guessing it's the o-rings, since I re-used old ones, and I'm just not known for being delicate/gentle when needed.
so, I'm looking on ebay for o-ring kits, and I notice there's a BIG difference between the brown:
now, it's been a while since I swapped them, and I'm going to buy the kit for the reds, but what the hell is that middle o-ring for? I don't really remember having to mess around with the middle ring.
Also, those "vents" down around the bottom... what are they? do they go to nothing?
