I have a Holley Black Pump and freshly rebuilt regulator. I had these on my drag car for two seasons. Very good condition. No problems. I just needed to upgrade my fuel pump due to more power! $90 + shipping for both the regulator and pump. Summit sells the pump for $260 and the regulator for $46. My price for both the pump and regulator is just $90 plus shipping. I also have a blue pump that I've been using as my spare. I had it on the same car previously for about 6 seasons. This pump is $207 on Summit. Mine is $30 plus shipping. Best way to contact me is at mikeforsythe@yahoo.com
