I am having a fuel pump problem.I took my boat to a local boat machanic with the problem that i wasnt getting enuogh fuel .So after all the ovious repairs new fuel tank new fuel line new diaphram,The problem still existed.At this point he put on a electric pump that runs constant.This gave me more fuel although it still wasnt the same as before the problem the first started.Also after the electric pump was installed the pump would drain my battery and also i was going through way to much fuel.So I did some more research and was told that i may have head gasket leak so this was also repaired.The problen didnt fix the fuel issue so im still haveing the problem that if i turn off the pump the motor starves of fuel.Can you help??
