Greetings.. 1977 CVX20 Sprint Gas Tank.
« on: March 30, 2021, 09:49:58 AM »
So I just bought a 77 sprint.... pretty nice boat as is - it will get nicer...

I notice these guys are running this FIST sized fuel filter under the gunwale on the starboard side of the boat. This tells me that likely the gas tank is rusty.

I was told on the CVX facebook group that replacing the tank is as easy as pulling the center console, pulling the kick boards, and then pulling the tank out (no deck splitting required thank GOD)...

With that all said - what kind of labor am I looking at to have someone do the work?

Anyone? Beuhler?

thanks!!

Have you checked/opened the fuel filter to see if it's full of gunk?   As with cars, rusty tanks can be boiled, cleaned, and lined to make them useable again, but it's generally advised to replace it with a poly tank so you never have to do it again.      You shouldn't have to split the hull, but you will have to remove a few things to get it out as you stated.

Welcome to the forum doc_  !

The filter could be a water separating / fuel filter, that is a good idea on a two stroke motor.

Can you find a brand / model ID on the  filter or a picture of it ?

Person doing repairs would also have to disconnect fuel fill hose, fuel line, tank breather tube, fuel gauge wires and tank hold down blocks.
I would guess one or two hours of labor ... Maybe ...

There are company's that do tank repair .. Do a search in your area.

First picture is a CVX20 Sprint ..
Other pictures are of a CV16, but your should look like this ..

these pics are EXACTLY what i was wanting to see... the deck/hull may eventually be split - but I would like to play for a summer before I do!

Will have LOTS more to post soon.
