What are you guys using for water PSI and vacuum line?
Rigging the boat and I'm wondering what guys are doing for mechanical water pressure and vacuum hose.
I believe the autometer gauges I have come with 1/8"NPT male fittings. My water "tap" on the intake is a -3AN male (it's welded in).
My vacuum port on the manifold is 1/8"NPT female.
Polyethylene tubing and brass compression fittings?
Thanks,
Rob

Brass compression for the vacuum on mine. The gauge fitting pretty much dictated the size for the pressure lines.

I bought other 1/8 line and ended up replacing it with this due to better durability. (oil pressure)

The long nuts are better

1/8" 1/2" 0.030" 50915K101
All my other mechanical gauges are rubber hose (like above) which holds up just fine too

My boat has 1/8" poly tubing for water psi with brass compression fittings. Never had an issue or leak.
I replaced the water psi line on my Pantera with 1/8" poly tubing as well. You just have to be very careful not let it get kinked when you are running it up to the dash.

The only line I'm running the brass compression fittings on is vacuum. Never a leak from any of them. I'm actually not sure what the other fittings are offhand. Likely AN

I ended up doing things twice when the poly I bought from Carr was too soft (Durometer 55D) and the brass ferule would damage the connection ends.
The one I listed above is much harder and durable, (Hard (Rockwell R110)) less likely to kink but not as hard as the 10' that comes with gauges originally. That doesn`t come back from a kink as easily.
