I've got 198,500 on mine and still rolling. Running 16-21 pressure and 2'cycle oil.

I have a Blue Chip pump, and I a m pleased. I am sorry to hear some customers had an issue when dealing with them. The reason I bought from them, is at the time the were the only vendor selling with a new computer also

My original pump started shuttering while cruising at about 200k, got it replaced then. The PO had put on a FASS in 2004 and that seemed to hold it together until the 200k. Got a rebuilt VP from DAP.
