The fix is replacing the leaking part.
ceck on the fuel injector header, there is a small nipple valve with a plastic cap. remove it and attach a pressure gauge.
leaking rings
The fuel pressure regulator is bad, one or more fuel injectors is leaking or the check valve in the fuel pump is faulty.
check your fuel pressure. With key on engine off it should be 35 - 45 lbs. It should be 5 or 10 lbs higher with engine running. It should hold pressure for 15 min. - within 5 lbs after key is turned off. If pressure is low, or if pressure bleeds down quickly something is leaking. If fuel lines are ok. Either check valve on fuel pump isn't holding, or one of the injectors is leaking, or the fuel pressure regulator is returning the fuel to the tank. cycle the key on and off a few times to build up pressure and seal off both supply and return fuel lines. if pressure still bleeds down one or more fuel injectors is leaking. if pressure holds, release the return fuel line if pressure bleeds down its the fuel pressure regulator that's leaking. if pressure holds release the supply line if pressure bleeds down now its the check valve on the fuel pump.

The fuel pressure relief valve is located Under the Plastic cover on the fuel rail.
Setting a code 45 means the oxygen sensor has detected a rich exhaust. There are several possible causes. Excess fuel pressure Leaking fuel injector Leaking fuel pressure regulator Intermittent throttle position sensor Faulty MAF
mine started leaking gas
CFI ? The fuel pressure regulator could be leaking.
It is probably not the fuel canister itself that is leaking.......on the back side of the canister ther is a small plastic drain valve.....this valve has an O-ring in it that dries up and fails causing the leak. the drain valve has a yellow valve control on it. It is a very cheap part and easy to fix.............Nick
It is located in the fuel rail very close to the fuel injectors it will have a plastic cap on it
