Hi All,
Looking for a little feedback from someone a little more knowledgeable than me. My brothers 96 GSX has always been a little temperamental. When it runs, it runs great. The ski has had the carbs rebuilt when the ski was first purchased, I want to say a new fuel pump was put on as well, and the electrical system was gone through and brought back working as it should. The one issue that has seemed to be a consistent issue is it being a hard start. It seems to have an issue that when off, the fuel flows out of the lines to the carb. I have checked for fuel leaks and have not found any. To get past this problem I put together the below diagram coming from the tank.
My question is, while the shutoff valve works great to isolate the electric pump output from the mechanical pull of the fuel, it is a pain in the ass to access to turn it off. Would putting a check valve in place of the shutoff valve cause the mechanical pump to work harder than it needs to? Right now the electric pump is really just to prime the system to start again.
