The fuel pressure regulator, however, is about $35 at AutoZone and is not that bad to replace. It comes with the torx security bit needed to remove/install the FPR on the spider with it in place in the motor. You'll need an upper intake/plenum gasket as well.
If you're flooding more on the passenger side, that's the culprit.
You'll need a 10mm deep socket along with a screwdriver that takes bits.
