***** System pressure should be around 90 PSI.
Its not the fuel pump that regulates the pressure, its the pressure
regulator at the end of the line that does it.
I think its clogged, or you have some other clog in the fuel system. Thats
why the pressure is so high.

Fuel pump ---> fuel filter---> fuel distributor ----> pressure
regulator -----> back to tank
