[s-cars] 95.5 S6A fuel pump check valve failing

[McCall, Randy]

I've been driving relatively trouble free for too long apparently!  My 95.5 S6A has recently started showing signs of hard starting - after it shuts down the cranking time has now gone way up.  I at first though perhaps the CPS was going south with some of the first hot weather we've had here in the Willamette valley, but I'm now more convinced that it's the check valve that isn't holding pressure in the fuel lines.  Car runs perfect once it gets fuel, but takes several tries to get it to kick off after I've driven and shut the car off for more than 10-15 minutes.

This is a chipped car with about 175K on the original fuel pump -presumably, as I don't have records of it being changed prior to when I bought it at about 92K.  Probably time to do a FP before it also fails...Any consensus on whether to replace the fuel pump with stock instead of other aftermarket choices, and does a stock FP include a new check valve?  Relaying the FP could be part of the replacement process as well as I see that is often a recommendation.

Thanks,
