That current draw does seem a bit high. What speed does your HPU use to drive your power steering? Can it be lowered? Reason I'm asking is because the current draw of the Toyota MR2 pump I'm using draws something like 4 amps at idle, and goes up to almost 50 amps when called upon to operate the rack.
