Pitometer

I recently replaced the Pitometer tube to my Honda speedo but the tube popped off the back of the speedo and started filling the console with water. Never had a reading on the speedo so I am guessing it is faulty. My question is, should there be something to stop the water travelling all the way up the pipe or is it just likely to be a faulty speedo?
Thanks

Ive never known anyone actually use one. They are notoriously unreliable and inaccurate. Id just blank it off at the engine end. It is an open ended pipe from engine to gauge. The gauge is just a pressure gauge calibrated in MPH.

I have that too. The solution in this case is to remove the speedo and fit a clock/voltmeter/USB charger.

Fair enough, I understand, just lay here on the couch & well talk about it
The tube is fine, otherwise it wouldnt have filled your console. The gauge will be goosed. They clog & corrode internally due to the saltwater. Youre going to have to swap it out or put something else in the hole. As youve discovered they are a PITA, Id bin it & put something else in there.
You might be able to poke about with a fine wire & un-block the gauge, or the whole thing may just be rust soup inside. Personally, the last thing Id want is a saltwater hose pipe leading straight into the console.

I reckon the tube is aged, too stretchy or simply too big. It won't matter whether the gauge is good or not, the pressure in the tube will be the same either way and obviously the tube to gauge connection can't handle the pressure.

However, dump the whole thing, as Pikey Dave said, the last thing you need is a console full of salt water.

Lie down in the dark and give yourself a talking to. If that doesn't work wrap some turns of fuse wire around the tube/nipple and twist off the ends using pliers.

Partial tube replacement took place, but as has been mentioned already, I think the gauge is corroded internally. I will take a better look and will probably swap it out. Thanks

They are a throw back to before GPS when estimating speed and dead reckoning were the only way to navigate. Sailing boats still use log wheels to measure speed through the water separately from speed over ground, but that is in a world where a few knots of tide matters. Even a brand new pito/speedo is probably only 20% and doesn't work at <10 knots in my experience!
