Glowing Red Cat

Help ! My 88 5.2 Liter Ramcharger is running rich again ! I changed the fuel pump a couple of months ago because it was running to rich and I diagnosed it to be the fuel pump over pressurizing. A couple of months later it seems to be doing it again. Is it a bad aftermarket replacment or is there something else ? The cat is glowing red again so I figure the fuel pump has crapped out ! Dosn't the regulator suppost to open up if there is too much fuel ? Any answers ?

if its running rich, check ur coolant temp sensor. if its bad, it can cause the truck to run rich.
