ECB what year did they start putting tanks in all the 31SS?

I had talked to Bruce at Sonic and I believe the answer was 97-98 and newer models....

I have to look. I was just in that compartment to install new fuel fills. I don't recall seeing a tank. But, it may have carpet in the way. There were some water hoses that didn't go anywhere.

There's no holding tank on my '03.

My buddies 2003 26 prowler had a portapotti but the holding tank was in place and just ready to be hooked up....

What were the extra water lines you referred to for?

If you look behind the dash, are there any hoses in there?

Anyone know where the tank is in a 386? I suspect that it is under the floor. I would like to install a gauge for both the waste and the fresh tanks. Don't like to guess how full the waste tank is :hitfan:

I wish I knew. They do not come into the area behind the dash. The only water line there is for the sink.

That's a bummer they didn't install it, with the tank it's a no brainer for an install. Getting that retrofit tank in is doable but a headache.

Anyone have any pictures of a install or steps on how you installed it?

I have '03 358, if you open the lower door in the bathroom and look aft, there is an access panel behind the A/C Unit if you have it. Mine was a board with black carpet, I had to peel the carpet off to access the screws that held it in place. Remove that panel and its directly behind that, its actually located directly below the driver's step under the steering wheel.

My down spout tube fell off and wasn't allowing me to pump anything out this season, it was certainly a $hitty job. All I can say is that I do not see how you could possibly replace it if something ever happened to the tank itself. If you have A/C installed I hope you're a small guy because they don't give you much room to work.
