Without modifying the internal pressure relief valve, I doubt it.   Simple
fix though - get a Bosch fuel pump from a car with the K-Jet system (ie
Volvo 264 or similar) as these operate at around 70psi continuous.    OTOH,
I've been told that bumping up the pressure too much can lead to the
injectors only opening intermittently , is this correct ??
