Fuel pressure testing on C4-100 (v6-2.8L) & C3-5000 (I5-turbo)

[Peter Golledge]

JC Whitney have a fuel pressure "kit" for CIS which has the correct 
metric adapters for the MC motor.  Not sure what fittings are on the 100 
though.  These are cheap but many (including I) have used them to 
resolve the ugly issues of CIS and incorrect pressures.
