[W126 Coupe] Fuel Pressure

[Dick Spellman]

Hi Hovsep:

If you have a set of gauges, just hook them up to the fuel distributor 
and run the fuel pump using a jumper until you get the system pressure.  
Remove the jumper and check the pressure drop after 30 minutes or so.  I 
think it's anything north of 3.0 bar on the 560.  If you are running an 
early model like the 380 or 500 it's 2.5 bar.  If it drops lower then 
it's the damper (accumulator).  This will also tell you if you are 
getting enough pressure from the pump(s).

See 07.3.120 for the complete test procedure.
