Engine Performance problem
1998 Chevy Silverado V8 Four Wheel Drive Automatic 160000 miles
my vehicle has the sequential fuel injection system. The fuel pressure regulator is located inside the upper intake plennum. When removeing the plennem to get to the regulator the book says to disconnect the vacum line from the regulator but I fine no vacum lline. I'm confused! The regulator has a vacum port but no line hooked to it. Am I to asume that the vacum is created inside the plennum and therfore needs no vac line? Can that regulator be bench tested?
have the same problem?
