In some applications, moisture may collect in the hose between the air inlet manifold and the transducer module (boost sensor). The moisture may cause transducer module failure, rust in the boost port of the transducer module, or a white powder buildup in the boost port of the transducer module. If moisture entry is a problem, do the procedure that follows.
Procedure
1. Remove the 3E-7402 Fitting that connects the boost hose to the top of the inlet air manifold. Discard the fitting. (If the boost hose is currently connected to the rear of the inlet air manifold, install a 3J-7355 Union and 9Y-6139 Hose to extend the hose to top of the manifold. The 7E-6045 Fitting in the rear of the manifold can be removed and reinstalled in the top of the manifold. Plug the hole in the rear of the manifold with a 9S-4191 Plug and 3J-1907 O-ring.
Location of components. Boost hose (1). 7E-6045 Tube Fitting And 3J-1907 O-ring (2). 8C-4985 Adapter Fitting (3). Inlet Air Manifold (4).
2. Install 8C-4985 Adapter Fitting (3) into the inlet air manifold (4) using 5P-3413 Pipe Sealant.
3. Install 7E-6045 Tube Fitting (2) and 3J-1907 O-ring into adapter fitting (3).
4. Remove boost hose (1) from the transducer module and blow out any moisture that may have collected.
5. Connect boost hose (1) to the transducer module and 7E-6045 Tube Fitting (2).
