On Board Water Tank Corrosion

Looking for suggestions to reinstall port after cutting away corrosion around inspection port. The overall tank is in good shape, it was just the part around the inspection port which corroded... I cut away all the brittle plastic and the rest is solid. It’s 16gal

1: Do I patch the hole and cut out the port hole again through the patch? (What would be a good patch)

2: Do I patch and cut a hole in a different place? (What would be a good patch)

3: Get a bigger port to size/fit the now bigger hole?

4: Cut the tank out for more storage space and get 2 more jerry cans?

5: Other options?

Here’s a pic of the situation...

Bigger port?

What corroded the tank? What plastic is the tank built from?

Is that a fiberglass tank? What is all that expanding foam for?

Epoxy and PE and PP tanks are resistant to most chemicals.

Yeah... I actually just found this in my spares... fits almost perfectly. A little sealant and it might be my solution.

Not sure, my guess would be water sitting around the old port and weakness from the original hole cut. I don’t know what plastic, but it’s probably the original 37 year old tank.

Re: On Board Water Tank Corrosion

Plastic does not "corrode".

The deck plate pictured is unsuited to sealing a water tank. You want something like this.

I suppose there’s a different word for it becoming a slightly darker color, hard and brittle.

That looks like a nice door. I’ll start asking around here in Australia for a similar item.

Thanks
