I have a pair of 3208TA's in my 1991 Princess 46 Riviera. The starboard boost pressure gauge reads zero but I know the engine is running fine. Can someone show me where the sending unit is for the gauge so I could check the wiring on my engine? Thanks in advance for the help as I am not sure where the senidng unit is for this gauge.

Dear ocgrant

Please contact your nearest dealer to get the needed support:

...or provide us with more information on your engine, like serial numbers etc.

Thanks.

OCgrant, pull the air filter off- you will see the injection pump and the base of the aftercooler/inlet manifold. THe sensor has to be there. Sounds like a wire has come off.

I have a similar issue on my Cat engines.  Both engines have completely different boost pressure numbers.  Do you know what  these numbers should be?

Cabo 35, need to know what horsespower 3208's you have, post the serial numbers and I can look at the test cell and PAR specs, then give you a range it can be. It's not entirely unusual for a pair of engines to have a psi or two different between them.
