Yanmar 3GM30 Oil pressure sensor AND switch?

[jfkal]

Does anyone know where to buy a dual sensor (pressure warning and pressure sensor) in one housing which fits the "hole" of the original sender or else an adapter to make this work?
Many thanks

Would you hear it in an engine bay with the engine running?

A Google search of "yanmar 3gm30 oil pressure switch" brings up what you want.

while searching for something, I came across a couple of threads in other forums (iirc) that discussed the idea, and I think they were suggesting two individual sensors tee d off the main hole. Didn't bookmark it so cannot find it now!
Pretty sure you can find it with a bit of googling.

cheers

I think it's a jokey comment.

ASAP supplies have T pieces which can be used to fit both a pressure gauge and a low pressure sensor. Not sure of the 3GM30 sizes, but worth a look...

The way I read it the op wants a oil pressure switch that has the sounder built it avoiding any wiring to a panel. Otherwise just buy a replacement pressure switch. What am I missing?

The obvious :


I would think it more likely that he wants to add an oil pressure gauge to a system that at the moment has a low pressure warning light and alarm buzzer but only one tapping point on the engine, currently occupied by the switch for the warning light and buzzer.

The neat solution ( I believe to be found on Beta engines) is a combined warning light switch and pressure transducer.

The simple solution is a tee piece into which the original switch and a separate pressure transducer can be fitted.

Sensor not the buzzer )

Not enough space for a tee.
Anyone know the thread size of the sender on the 3GM30?

Even for something like this

BUT
I believe may be a spare port on a 3GM30 where the pressure sensor can be fitted.

 

[jfkal]

Where would that spare be?

 

[VicS]

Dont know

Does this photo, found on t'interweb, help you?
