The Chopper Compendium

i was just wondering if most tanks you order online or from a catalog come pre-sealed to gas. i guess i could ask that on the website or through customer service. but i like getting replies from you guys.

nope never trust em always pressure test the welds and seal em up

I'm with Curt. Best tank sealer is good welds.

Ditto

even if i weld em myself id check em everyone has a bad day sometimes

i understand that good welds are super important but i think i was meaning if gas tanks come with some kind of liquid sealer that is poured into the tank and coats the inside of the tank to prevent the metal from rusting and being eaten away by the gas. that's what i should have asked.

i have seen some factory tanks sealed but ive never seen a aftermarket tank that was

Gas doesn't eat metal.

Want to block rust? Screw sealer. Go to caswellplating.com and by some flash copper solution.
All you'll need is a trickle charger, acetone, some 1/2" copper tubing as your anode and some gauze to
wrap the anode with to insulate it from the tank. In about an hour or so you'll have a copper lined
fuel tank.

hhmm..interesting..good idea!

i guess if i used what little brain i have left, i would have figured out that the gas tanks that come on cars/trucks are most likely not coated with anything and are just bare metal and that they don't get eaten through by the gas either.

The new ethanol fuels mandated by the US Feds gather moisture from the air, and if it sits in a tank for extended periods,
the water separates and cause rust corrosion inside the tank.

i read that somewhere, too. ethanol soaks up moisture, hence all the water-removing fuel treatments we have.

Saw the latest issue of Horse. They have an article with data on ethanol fuels.

I was only flipin thru it at a store with free WiFi. I was going to start a thread or continue my rant, "butt", this is a highly dynamic situation that dictates my attention.
