PSI

[wal1809]

Does anyone know off of the top of their head what the PSI rating on the fuel system for a DD 6v92?  I think I remember 65 pounds but I have to be sure.

50 to 70 lbs Wayne depending on the orifice in the return line,the relief valve on the pump is set at 85 lbs for the standard pump with 1/4 in gears  

good luck

I will add that those numbers are taken at the secondary filter outlet, at full load.
