91 Bird leaking gas

:1zhelp: My 91 Sunbird 2.0 OHC is leaking gas by the throttle body injector and I was wondering if anyone had any idea why. :uhoh: I can get into it and might have to.
Thanks

check the fuel pressure regulator,its on the fuel rail that feeds the injectors,there is a vacuum hose conected to it,it looks like a small round cylinder.pull hose off,if gas comes out replace regulator
