Yes. I believe so. Can you tell me what the purpose of those are?  Typical speedos and pick-ups do not have these. I assume they are needed for these types of speedos.?.

also, do they ever go bad?  Any reason to check/change them while the tank is out?

Appreciatively,

Indmar recommends a different routing so the manifolds are cooled all of the time and not just after the thermostat opens.  Several threads here discuss it.

My dealer gave me the same recommendation but I assumed they were just looking for more ways to generate revenue since I haven't had an issue with overheating over 1400 hours. I'll read through these threads to get more background.  Much appreciated!

Sounds like you are describing the connection to the two pitot tubes that go to the two air guide speedos

Hello,

New to the crew here. Just purchased an ‘older’ school boat. Done with the surf and wakeboard scene!

yesterday I was beginning to remove the fuel tank in my newly acquired 1995 Malibu Response due to the fact the speedos do not function. PO had chipmunks living in it a bit and they had chewed some wiring. 

I searched this site but saw no info on the removal of tank so ventured forth and got it out (a little pain;)

It turns out the critters had chewed through the speedo tubes behind the tank. *Did you know you can’t get to the lines without the removal of the tank?  Too bad the engineers didn’t make that a bit easier  Anyway, I was going to ask if anyone had done this process but too late now. 
 

I do have a remaining question though… what is the purpose of the two tubes in the back corners against the transom?  The speedo hoses run to, and out of these tubes. No other boat I have had or worked on have had these (and as a younger person I worked for a boat company in their rig shop. 
 

appreciate the knowledge here,

Fritz

Can anyone provide a valid email or update on them?

Thanks
