Re: how to rebuild fuel pressure regulator
If you are talking about the pressure regulator part, it's pretty simple. Remove the 19mm (I think) heax brass plug. Inside will be a spring and valve spool piece. Check the bore and valve spool for scoring and make sure the spring is in good shape. The spring will go on the spool piece bore and the nub on the end of the brass plug. If you are removing the regulator body from the fuel bowl, don't drop the screen assembly, bolts, or the little white plastic check ball (its on the outboard side of the screen) down into the valley of death. If you need new guts for the regulator (just get the CA version) or the screen assembly here are the parts:
