The car

 

1992 1.6 engine/JR supercharger running 6 psi/Pierburg Pump/BEGI AFPR (old
style) car has 150,000 miles on it and the Sebring system has been on it for
about 35k.

 

The problem is that I don't develop enough fuel pressure.

 

Was running about 75-80 psi in the past.  Now I can't get more than 65 and
it doesn't hold that.

 

No WB but the NB unit never shows the A/F going full rich anymore.

 

Changed the fuel filter.  Made sure the Pierburg is running.

 

Could the tank pump be bad and the Pierburg isn't capable of overcoming the
load of a bad tank pump??

 

Or could the problem just be the AFPR??  I turned the adjustment screw a
little and got no real difference in the pressures.  I hate to mess with the
setting on it since the car was running well and the thing is a PITA to
adjust.
