I don't think your FP is your problem, you're probably leaking somewhere on the outside (or a leaking injector) and the vent system is sucking the fuel vapor into the cab.
As 8mud said, get the flashlight out, and start tracing things... I know I've been on a kick about using fuel pressure testers (saved me a lot of headache in the last few days), but it's worth doing. Another possibility is if you have an exhaust leak (common in your year) and you're getting extra unburned fuel out the exhaust this can also cause it.
However here's what I would check in order from easiest to hardest:
1) Turn the vehicle on with the hood up, check the injectors, any leaking will be obvious.
2) With the vehicle still on, pull the vacuum connector to the fuel pressure regulator, see if there is any gas leaking out (again should be obvious)
3) while it's still on, look under the vehicle for any places where fuel is leaking
4) listen for any kind of exhaust leak
If you have a leaking injector, determine whether it's the seal or the injector, replace as necessary
If your FPR is leaking - replace
If you notice gas leaking out of the vehicle, try to determine where, the rubber hoses that provide both supply and return are prone to rotting with ethanol gas.
If you have an exhaust leak, check and see if the vehicle is running rich.
Also, there may be a defect in your vapor recovery system, check and see if you're getting fuel all the way up/into your charcoal canister, it's possible it is saturated with fuel, which may mean your engine isn't sucking the vapors out and burning them. This IIRC is controlled by the vacuum system which opens up a valve at the air box (this is what that really big tube that goes into the airbox is supposed to do, usually it mounts near the big rubber hose that connects the airbox to the engine.
