So I reattached the vacuum line for the FPR and had perviously replaced the line between the intake manifold and the PCV. Upon taking the top of the intake off I found the vacuum line had a kink in it and was planning to replace it with a better line. I removed it from the PCV and found gas in the line. I spoke with my local Autozone guys who said that this is likely caused by a bad FPR. I haven't put the intake back on now that the vacuum line to the FPR is solid. So, would the leak in the vacuum line cause the excess fuel or is it more likely just the vacuum?
