Chevy 2500 Fuel Injection System Q. Need specific removal and replacement instructions for a fuel injection system for 1998 Chevy PU, 2500 series, 5.7 litre engine with automatic transmission. Can you help? Need instructional ASAP. Thank you...

A. If you are talking about the injectors themselves, you need to pull the upper plenum. My suggestion would be to just take the whole intake manifold off and do it on a bench because the intake gaskets are probably shot anyway. Then it's simple to get the upper plenum off and access the individual injectors and pressure regulator.
