I searched for three weeks for a replacement fuel pump or rebuild kit for my 1968 Mercruiser 120 I/O. No one had the Mercruiser part number in stock, or any recommendations on where to go. The Mercruiser service desk gave me the AC part number and another part number and a part number of ECN 6790. He wasn't sure what the ECN number was about. With this information in hand, the internet sent me to AAAA. I ordered the pump, it was delivered on time, and installed just like the AC original. The engine fired up nicely, and I now have one 45 minute shakedown run on it. I am extremely pleased with my interaction with AAAA and the apparent quality of the pump.
