You definitely can do this on your own.

It is a messy job and you will get some battle scars though.

You can have a quality tank builder like Patriot Marine in New Jersey make you a new tank, and Grady White customer service will e mail you the diagram for the build based on your hull/year.

Did mine on my '87 Seafarer 2 years ago.

Any questions come up about changing out the tanks just holler!

Many members on here have done the same project.

The removal required cutting the hole open about a 1/2 inch I used a angle grinder with a cutoff wheel. The hard part is replacing the fuel fill and vent lines. There are plenty of great threads on this here. It’s a weekend project start to finish if you have tank. I probably could do in a day if push came to shove. BTW where in NJ are you from?

It's definitely a owner project for sure. No need to pay someone to do it. Let's you get to know your boat better. I replaced both main and auxiliary tanks in my '04 228. Replace the hoses also while there. You'll be ahead in the end.

I had SP Sheetmetal do a tank for my Mako a few years ago. They were in Barnegat at that time but have since moved to Dennisville. Great people to work with and an outstanding product. I’ll have them do my tank for my 226 when I replace it next spring. I had originally planned to do it this year but a collapsed sewer line a few months ago took financial precedent.

What year is your 226? What condition are the tanks in? I thought mine looked to be in good condition, especially being 20 yes old but now I am wondering

I wouldn't consider this a typical DIY job. Some factors can make a somewhat hard job a really big and expensive job. Two things in particular; A deck that has to be cut out ( no caulked in panel) or the discovery of structural issues like rotten bulkheads, stringers or deck panels.
Your hull is 34 years old and it is pretty common to find some issues. So if you consider yourself handy, can afford the extra time it may take to do the job, go for it.

Is the deck just screwed in like all the other Grady White boats? I have the same model and replaced fuel tanks. No cutting of decks at all.
FYI, the deck on my 2001 208 has no panel to remove. If you want to replace the tank, you have to cut the deck. I am not sure what years have a panel and I wonder why mine doesn't. My tank is poly and perhaps the engineers figured that it would never have to be replaced:)
