Yea, its tight, and I replaced te WIF sensor with the alluminum plug from merchant. The bleeder screw they sent me doesn't fit though, so my old plastic one could be leaking....

the bleeder screw m10x1.5 bolt with an o-ring on it, and its 7mm long.
so you can find a m10x1.5 flang head bolt and put an oring on it that will fit on there. you can find all that stuff at ace or sears for about one dollar
