[QUOTE="PSG-1, post: 264889, member: 6937"] Yes, that's an OE design, having the fuel pump mounted to the engine plate. Your fuel pump should be a pentagonal-shaped pump, with 1 inlet, 3 outlets, and a pulser line. Try this part number: [b][i] DF 62-702[/i][/b] You might see a picture of a fuel pump that only has two outlets instead of 3, but they both use the same diaphragms and check valves. I've rebuilt a few of these. As far as the high speed miss.....make sure that you have the CDI mounted in a manner that leaves some slack for the wires. I had this problem with my boat, had the CDI mounted a little too far back, and it had the rear plug wire pulled tight, where it would run like crap at idle, then it would occasionally straighten out at high speed, then go back to running like a POS at idle. Took me forever to figure out the obvious, the connection of spark plug wire to the boot was being interrupted from engine vibration, etc. I moved the CDI up a few inches closer to the engine, and that problem went away.
