I'm transplanting a PH2 172 engine into a different shell, and can't use the clio fuel pump/collector/regulator unit.  How do I modify the fuel rail to use a regulator?  It looks like I can fit the regulator out of the tank, so it should just be a case of drilling some holes....  How does the fuel return line attach to the fuel rail?  More to the point, where can I get the parts required/ part numbers etc..
 
Thanks
Andy
