Super Jet any one build there own tanks?

just currious if anyone has made a fiberglass tank for there ski or is aluminum the way to go pics of custom tanks

Aluminum is the only way to go IMHO. There have been a few who have made their own tanks. The great thing, you can add capacity without adding size. Imagine all of those rounded corners, if you were to square them off, you could probably add a gallon to your capacity, or make a tank that's the same capacity, but not as tall, helping reduce your center of gravity, or a bit of both. You could build in a battery holder, sight tube, internal fill, baffles, trap doors, whatever floats your boat.

My step-dad makes fuel tanks for a living for yachts and fishing boats. We've talked about it quite a bit.

whats the advantage to a internal fill just prefrence and what kind of cap do you use what size aluminum plate ??

I wouldnt do a fiberglass tank the fuel would prob break it down over time

there is no advantage to internal fill its a pain in the azz to re-fill.... i guess you might get a little more fuel in...

No advantage really, just something that can be built in if you like that. I pop my hood when I fill anyways cause I hate spilling gas, so internal fill might actually be more convenient for me.

For a cap, you can buy a fancy aluminum filler neck and matching cap from Blowsion, or go to Jegs or Summit and look up fuel cell caps. You can buy the whole cap/flange unit if you want to go that way.

If I were building one, I'd probably use 1/8".

X2 No advantage to internal fuel, unless you do hood tricks/ fountains. The external gas cap isn't comfortable to sit/slide on, and shorts get caught on it. Some on here have learned that internal filling can lead to gas spills and fires/explosions.

my water box has come close to just about melting a hole in the tank and no mater how its adjusted it sits against it will work for now just getting ideas for maybe a winter project so i dont have to worry about it melting through and spilling gas

Because you are not to sit there.

your waterbox shouldnt be getting that hot.

personally, i wouldnt change the tank unless i had to.

I started building a custom tank last year and bailed on it when I accidentally made it 1/2" too wide. I plan to pick that project back up fairly soon. Epoxy resin should resist fuel for decades. My original plan was to use fuel tank sealant in my tank anyway but that was to prevent weeping through tiny pores in the layup and not really because the epoxy would degrade.

If you go on a boating forum, there will be guys complaining about their fiberglass tanks needing replacement because they are getting soft or degrading. If you pay attention though, most of those guys are talking about boats made in the 70's and you can pretty much guarantee that most boat owners have seriously neglected their boats and left old fuel in the tank for at least 9 months out of the year.

Are you kidding? my signature move is to bump and grind all around the opening. You should see it, the ladies go wild.

I used to have an SXI Pro, which came stock with a very small tank, I think 4 gal? At that time I liked to cruise up the river for some long distance rides so I needed a bigger tank. I ended up making a 7 gallon capacity one out of Aluminum which worked perfectly. I first made a mock up out of card board and then took it to a shop that made custom dune buggy stuff. They cut the Aluminum from my patterns and welded it together for me. I used an OEM Super jet fuel pick up and had threaded inserts installed for the breather and reserve lines. I had two made and it ended up costing around $300, and this was probably like 15 yrs ago so it’s kind of pricey. Unless you want to make a smaller tank for freestyle or a larger tank for long hauls I would just buy a new OEM one. A new OEM SJ tank is only $135 from Greater Yamaha

ask the guys who have Skater Boats about Epoxy Resin tanks..... They are comming apart
