(is that correct terminology)
In a moment of stupidity about 7 years ago I kicked my module which is mounted towards the front of the bulkhead under the drivers dash and broke off the piece that the hoses mount to. After cruising for about 10 minutes I noticed my entire cockpit carpet was soaked. Took me all of about 3 minutes to realize that the water was just spraying out of the tubes that were now open. Problem was no water comes through unless you are cruising. I just clamped off the tubes and flipped up the pickups on the transom. Perfect pass speedo is fine for me.
So yes, there is water 'pressure' in those tubes. I've never heard of one 'leaking' and blowing a module but it could get the area wet, theoretically.
