hi -
We are looking for the location to installl the water pressure sensor... any ideas?

it's the drain on the Side of the block...my bad.

I've seen them installed into one of the block drain
ports too.

If you were to do that, I'd put a tee fitting on it,
so you could still retain the blue plug drain fitting.

Yeah, we discussed the block drain option... the only issue there is blockage from sand and other debris... The engines have super chillers too... not sure if that limits the space on the back side....

My H2O PSI is taken off the L side of the block. It's never had an issue. If the gauge gets plugged with sand its time to clean the block. An extra warning device.
