If you are getting that much fuel you may have one of 4 issues.
1) Did you remove the rubber cover on the new FPR.
2) You possibly have a stuck injector.
3) You possibly have a bad fuel manager, if you have one.
4) You have a leak on the vacuum line to the FPR.
For the FPR, pull the vacuum line at the FPR and turn the key on. If fuel is coming out of that vacuum port then your new FPR is bad. If the hose to the FPR is leaking, it will act as if you are WOT all of the time. That is the lowest vacuum scenario and when you'd need the most fuel. At idle it will increase rail pressure to maximum, really pouring it in. With that said, I'm not sure I've ever heard about raw fuel making its way out the exhaust. That's a lot of fuel.
