I have 95 Mercury 200 EFI the high pressure fuel pump went out I replaced it so now it burns gas like crazy. When the boat is parked with motor in stowed position gas leaks off the scag not a lot but enough. Has or does anyone know what is causing this and a solution to the problem?

Where is the gas coming from would be my first question. That should narrow it down quite a bit. Just a wild guess, but I would check all the gaskets and fuel lines where you replaced the pump.

It appears to be coming from the exhaust I can't find any leaks from hoses or anything

check tha mechanical pump for holes/tears in diaphragm .. check fuel pressure and regulator.. does tha pump cycle off when motor is not running and key on?

Fist thing I would do is take the cowl off and then squeeze the primer bulb and see if you see gas coming out anywhere. It could be a stuck float, cracked fuel line, cracked fuel pump, etc. Is is just gas coming out or oil and gas? Could be the VRO going out also.

Pumping the bulb is a good idea.That is how I found a leak on my carbed Merc. It was the cross feed lines.
