I just put a new BG500 pump on the Daytona last year as the old one (10+ years) started leaking. I figured I would send it in for a rebuild to keep as a spare. The new engine was laying down during the run and I found out the new pump was only putting out 8 1/2 pounds at the pump. (supposed to be 25 pounds) The regulator on the pump must be screwed up because that's all it would put out. Wrecked the car that weekend and procrastinated and did not send them in for repair. Oh well.!!!
