It's a pretty tight fit into the IM. I bored out the lower seals. You could also go to Home Depot or something and get faucet washers (5/8" i.d., i think...). I lost one and had to improvise.

It's a b1tch, but for $50 ... can't beat it. Yes, OBD2 clips do not fit. Just go to the auto store or something and buy some. I got all (4) clips for $25. Resistor box cost me $30.

P.S. Oh, make sure the fuel rail is bolted on nicely because an injector popping out is NOT good.
