The fuel pressure is set by the regulator on the inlet manifold. Nearly any pump from any injection volvo will provide enough fuel for standard power for a B230FT. The 360 GLT pump will drive it.

If you ave any doubts then fit a pressure gauge inside, or just upgrade it.
They have a limited life as the DC brushes wear out, my 940 one failed after around 160K.
