Default Home built Aluminum in floor fuel tanks

Has anyone fabricated their own in floor, or above floor fuel tanks? I am looking to replace my existing in floor 35 gallon fuel tank an am considering making my own.
Is there anything I should be aware of for certifying the tank. Or is it required?

Thanks, Steve

Gotta be tested and certified. Most shops that build them are certified to conduct the test and tag them as a certified tank. Rules for building tanks and testing them are available on the internet. As far as finding someone to certify a tank you built, that might be difficult.

I thought about doing one for my old boat, but quickly realized it was going to be more work that a tank is worth. I ended up having one built from a place in Eugene area, I cannot remember who it was though, or know if they are still in business.

As said there is pressure testing that needs to be done properly. There is also some design considerations for structural integrity with regards to baffle placing and such. And using only aluminum fittings, no brass like some manufacturers cheap out with.

I found it to not be worth it to make tanks and I make a living bending and welding aluminum on boats. I really can't beat the price of coastal in Bellingham when you add in the cost of the aluminum, fittings, sending units, bending and welding, rate of decay pressure testing, etc. I can buy their tanks built to whatever dimensions I need and have them delivered for cheaper and not have to worry about the certification stuff since they all are certified. They build for many boat manufacturers around here.

That said I've built them for my own boats .

Thanks for the reply guys. I thought that getting the tank certified would be my hang up.
I guess another thing I didn’t consider is the liability factor if it failed.
