Re: fuel leaking from intake
Most excess fuel in the intake has something to do with the fuel pressure regulator (diaphragm) rupturing and leaking down to the vacuum hose attached to the fuel pressure regulator and gets sucked in the intake.
Leave the vacuum hose on the fuel pressure regulator attached but the other end of the vacuum hose should be disconnected from the intake and check for fuel leaking from the disconnected vacuum hose. If that is the case then the fuel pressure regulator needs replacement. The fuel pressure regulator is suppose to just adjust the diaphragm in conjunction with the vacuum applied in the intake. Nothing is pulled from the fuel pressure regulator by the vacuum hose but just adjust the diaphragm. The problem arised when the diaphragm is ruptured and allowing the fuel now to enter the ruptured diaphragm and into the intake and there you have excess fuel in intake and floods the engine. |
