My most INSANE FUEL TANK build yet! - SECRECTS REVEALED!

TWO TANKS!, 280L of fuel, and one BEAST OF A BOAT! My most challenging fuel tank build yet. The owner needed extra fuel on his 28' Pursuit to handle fishing trips deep offshore. These tanks had to be extra strong to handle the long hours at sea. If they failed it could leave him stranded in the open ocean and spell disaster for the crew.
In this video, I reveal the most important secrets boat builders don't want you to know. Learn how you to can build beautiful high-quality fuel tanks with these simple tips. Take your aluminum welding skills to the next level. You will learn how to stop galvanic corrosion with Delrin plastic and proper cleaning technics for aluminum. Plus much more!

Wow, really neat build.

[@gregepp3082]

Thanks Gary!

[@tinybrown6710]

Watched I think it was your boat building video as you say about a year ago, when you questioned your ability. Glad to see that you stuck with it and increased your skill level. The tanks look amazing, you should be proud of yourself and your tenacity in overcoming your doubts. Well done....

[@gregepp3082]

wow, thanks! Tiny Brown. I've learned a lot, so much more to learn it's an ongoing and never-ending process. I do struggle with putting out content but also recognize as I learn what I have taught might be incorrect.

[@brianbures4478]

Great build !!! I too have gone to a Tig button it is so much easier to work with !! Again great build!!

[@rallwest]

I acknowledge you for your detail orientation in your presentation, it's a pleasure to watch and listen. I've been an actor for decades and few people are as concise and prepared to go along with their knowledge, and babble or go "off topic," which you don't do. Your videos are easy to learn from. Thank you and I look forward to learning more.

[@gregepp3082]

Thank you that is a huge compliment. I suppose Toastmasters pays off lol.

Nice vid bro! Subscribed!

Thanks, dude!

Good video mate always love a bit of Aluminium welding Was the torch switch a variable one Cheers from Aus

[@gregepp3082]

Thanks for watching!!! Yes it's miller roller switch style. I generally set the machine for 220amps and roll the switch to the max, backing off slightly as the part heats up. you don't have the same control as a foot pedal but greater flexibility in movement. It's worth the trade-off. You also don't have to drag that pedal and cable around.

Excellent work! About the little overlap of the aluminum sheets when welding the joints or edges, could you educate me the benefits of doing it that way? Other folks I've seen there was no overlap. I'd like to know the difference. Is the weld going to be stronger? Other thing is the thickness of the aluminum? I thought you said 3/16? Thanks in advance

[@110welding]

Excellent workmanship... Question: What is a rough time to complete this once you have all the parts for it?

[@gregepp3082]

I average 1.5" per minute normally. That includes all the weld prep, unpackaging the parts, etc.

[@rytime700]

I am 712 sub! Hell yea I've been early on alota channels that have went very very big.

[@gregepp3082]

lets hope they take off one day! :)

[@williamcostin4905]

Do you weld the inside ?

[@gregepp3082]

Not possible normally the way tanks are constructed. They are normally made like a clam shell. There is no way to get inside.

[@carlfriesen4888]

Hey cool gas tank. I was wondering how the tank mounts in the hull. Does the weight rest on the hull or is it suspended with the weight on those bolts? I wanted to make a tank for my boat and wasn’t sure if people ever had problems with wear from the tank rubbing on the hull?

[@gregepp3082]

It was mounted with bolts holding the weight. Surrounded by Delrin bushing. I built the tank out of 3/16 (1/8 is the norm) It also had a lot of baffling for the tank size. This was to give it the internal structure to take the weight. Great question!

[@gregepp3082]

You definitely do not want to rub on the hull. What I have seen though is corrosion happens anywhere that aluminum and water touch for long periods. (it will eat through the tank) You can also have galvanic corrosion with stainless and aluminum. Given those factors, I overbuilt this tank. However most tanks last 30 years. So this is definitely overkill. Good luck with your build!

[@carlfriesen4888]

@@gregepp3082 Thanks for your feedback! I’m going to give it a shot

[@3Beehivesto300]

What filler rod did you use on the tanks?

[@gregepp3082]

would have been 1/8 5256

[@WaterLandAdventures]

Did you mean to say 5356?

[@gregepp3082]

Filler rod would be 5356, base material would be 5052 @@WaterLandAdventures

Really nice work thank you for the video and ideas!
