Itasca Horizon 2005 Freshwater Tank Leaks from the bottom of the freshwater tank

[Pajarodilady]

Our 2005 Itasca Horizon has 2 leaks in the connectors below the fresh water tank in the back of the first compartment after the side entrance door.
I removed the Plate cover, which is very rusted, and discovered it has been leaking for a while.
Has anyone replaced the leaking connectors? There are 2 on the bottom of the tank that go to a Tee and then into the shutoff hose. In a 2005, I hope not to crack the freshwater tank by applying pressure to changing the plumbing fittings.
Any advice would be appreciated. Also the plate cover should be replaced. Any idea where to get that? Part# 134297-02-02B.

That is certainly a different way to go! Two tanks and connect them must mean there was some major reason for not using a single tank?/
But that is water under the bridge!
the bigger question might be what type fitting that is at the base of the tank. Is at a threaded fitting that goes into the part on the a tank or is it a glue joint?
I will say it looks like a bear to fix as things are going to be hard to reach and hard to get done!
If it is a glue joint, there is a tool o remove the fitting from the hub. I have always been able to avoid doing that and never felt good about saying I COULD it it without causing me more problems than fixing!

Something to consider and ask around about the wisdom of trying this? No experience here!
Then there is also the idea of asking how much trauma you want to get this fixed right versus getting something to get by?
Possibly a shallow drip pan formed to catch the drips and a tube to lead the water down and out underneath is one thought?
When RV get older, I begin to do less major work to keep them OEM shape as it never seems to happen anyway!

The 2 fittings below the water tank were threaded. They were able to be removed up to the Tee. The problem is finding replacement parts. Between the threaded elbow and the Tee is a clear tube. It is a Kuriyama ID 1.5" x OD 1-5/8". I need to find this replacement tube. I will purchase 1-2 feet because the other tubes will also be replaced. I have called around but have not had any luck. Even our local RV dealership has no idea.
I will be calling around after the Memorial Day holiday to find a vendor for this part.

That would seem to be some major progress on the part that had me wondering but those are not any type of fitting I have seen.
Is that some type of crimped connection between the el and tubing or might it be good to replace with some more common item?

If this only has the pressure of the standing water in the tank and road movement, maybe a simple screw type clamp would do and be much easier to find?
I have done enough of the normal PVC/CPVC pipe that I love it.
I might go for just backing away from this type and replace els, tee, and tubing down tot eh straight piece at the last!
After this much time, I'm kind of hard to jar out of what I've been doing!

Certainly can't say I have done anything with plumbing of that sort but just throwing some ideas out on what I might chase!

Looking around I found this info on the tube??

WOW! looks like they went for super odd and super strong?

... don't know how much room you have or your willingness to reconfigure. I would look into running a PVC line near enough to the side that you could reach a new valve and bypass the old one.
