I have a 2000 Launch with the Assault MPEFI engine. Fuel pressure is 10 psi. This motor has 2 fuel pumps and 2 filters. I've changed the filters with no improvement. I believe the problem is the high pressure pump, which is inside a cooling canister on the front of the motor. Apparently this part is no longer available from Indmar. Skidim shows a non-cooled pump as the replacement, and a kit with an elbow and some plugs to bypass the cooling. Has anyone done this? Any tips?
