How do you prime one? We had to have the injector pump rebuilt and haven't had any luck getting it primed yet. Dt
Old series PT Pump? Plug on top of pump, the smaller of two aside the shut off solenoid(1/8P). Get that open then use a small diesel rated electric pump and push fuel up the feed hose thru the filter to the pump. Easiest on the entire system I have found, these have PDP transfer pumps inside, should pull prime if lines and filter are full.
