Hi Everyone,
I have a 2003 Mercruiser 4.3 two barrel carb with electric choke and electic fuel pump. The carb had been replaced twice, the fuel pump has also been replaced twice. The fuel is coming out of the top of the carb and the fuel pressure is too high. We added a Holley adjustable fuel regulator and every time we run it, the pressure changes on its own.
Any ideas as to why?
