I installed an HPOP on a DT 466 E today . Now this is not the first time I have done this . The first time I replaced one I cranked on that engine for probably 10 minutes or more .With cool downs I was at it for 30 minutes . Is there a right way to start the engine after install ? The first one I was questioning if the pump I pulled was bad . This is one that died and would never start . During cranking I showed 200 lbs .Thanks
