Changing a return into a returnless fuel system?

[Benno]

no fuel pressure sensor, just runs a small fixed regulator right beside the intank pump.
the regulator holds a fixed pressure through out the fuel system, it's just to stop fuel being cycled through a hot fuel rail(to limit HC emissions from tank)

speaking of fuel pressure sensors - any suggestions as to which car (in wrecking yards) might have these. I was considering trying n oil presure sendor but something designed for fuel might be better (sorry for the OT question).
