I've rebuilt all 6 carburetors, installed new OEM Fuel Pumps, Fuel Pump pressure checks out at @ 2psi - 3psi. and holds it at that pressure, the vapor pump holds a vacuum, the vapor separator float is set correctly, the needle is not stuck (assume it's seating correctly). Fuel lines are not kinked or restricted. The primer bulb pumps till it's firm and stays that way. The engine starts right off, but will not run for long (a minute or two or less). I've run the engine from a separate tank with fresh fuel. My assumption is that the engine is not getting fuel, but don't know where else to look. The engine is a 1992 150hp Evinrude. It was originally a VRO set up, but changed it a couple of years back to two carburetors using premixed (50-1) fuel in the tank. The VRO kept failing on me. Any thoughts on where to look next or what other tests I can run?
