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

[Graham Hicks]

You are on borrowed time for sure with 175 on the original pump, but the fuel pressure regulator (on the end of the fuel rail, not included with a pump) would be a good starting point too.
I would replace the fuel filter too.

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.

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.
