Can someone provide me with the correct system pressure and control pressure (cold & warm)specs for a 117.961 motor? Also, what is the delivery specs for the fuel pump?

Thanks,
Jack

Do either of you have access to these specs? I know it takes time from your day to look this up and I appreciate anything you can provide.

Cold control pressure depends on temperature.

fuel press at 68degF = 1.2 to 1.5 bar
fuel press at operating temp is 3.4 to 3.8 bar
system pressure is 5.2 to 5.6 bar
a bar is approx 14.5 lb@sq"
