Heater Hose Fitting for 5.0 CFI Intake Manifold November 18, 2022, 09:13:01 PM Looking for a heater hose fitting that installs into the intake manifold on a 1984 model 5.0 CFI engine. This fitting can accommodate a heater hose and a coolant temperature sensor. Seems like this fitting was only included with the OEM intake manifold. I cannot find a part number for the fitting and new aftermarket fittings are not available. Any sources out there for a used fitting? Thanks!
