It'* about time on the pump. Let'* get a key on/ignition off check, then idle, then idle with the vac line pulled off the regulator.
My 93 already has a new one, and my 95 is due.

The key on key off pressure was low also. I can't remember the exact number. So what replacement pump should I go with. I'm planning on modding this motor eventually so I'll want the best pump.
