The FPR was dumping gas, so it was replaced with a Standard Ignition Fuel Injection Pressure Regulator PR234. The plenum gaskets didn't survive, so they were replaced with Fel-Pro Plenum Gasket Set MS90505. Unlike most FPR failures which involve a diaphragm rupture leaking into the vacuum line & intake, this one leaked around the diaphragm and out the swages (both of them), probably due to the rubber being dried out & shrunken by the ethanol in modern gas. Hopefully, the replacement is designed to tolerate it better.
