I have a similar issue with a 2002 Boxster that I'm working on. Except the one that I have is a returnless system. I have already replaced parts: pump and sender unit. I get little pressure at my rails, 25psi while running and misfire on cyl 1 and 2; 35 psi engine off, pump on. I have also checked pressure at the output of the sender unit and pump. 40psi at output of sender and 60 psi at the pump (outside of car). Is there anything I'm missing, is there something to do with the EVAP or do I possibly have bad new parts? Any wisdom is much appreciated, thank you.
