[V8] fuel pressure regulator

[Scott Phillips]

Ed, 

Page 37 of the service training:  The FPR sets the pressure to 4 Bar
(58psi). The OE Fuel pump (Bosch 0 580 254 040) puts out 6.5 Bar.  Be
careful, the "looks the same" 944 Turbo uses a 2.5 Bar setting. That one
looks however to be ok, it also interchanges to from a (Euro) UrS4 V8
4.2.

HTH.

Saw an eBay auction for a FPR that showed application to our V8s in
addition to some 1990's Porsches.  It looks the same, but is cheaper.
AutohausAZ indicates it is a 3.8 bar regulator.  The Bosch p/n for it
ends in 287 whereas the one "spec'd" for the V8 ends in 298.
(0280160287 vs.
0280160298)
 
I can't find a pressure rating for the V8 one. There are other sites
that indicate the 287 part can be used on the 90-94 V8.  It's about 50
bux cheaper, so worth exploring IMO.
 
Thanks in advance for any input.
