Fuel proof epoxy?

[Techno]

Any one know if there is something sold like this? I need to build a tank.
I know epoxy is good enough but I would rather buy a product that says that it can be used for gas.

Techno,
Go to a Model or Hobby shop . They may not have the sizes you need but they can give you the manufacturers number.

As far as I know West System products are fuel proof.

Techno,

I have 2 gas tanks that were patched with J B Weld. One has been in the boat for over a year and the other came out of a round and round race boat. Neither has shown any sign of leakage. J B Weld is some amazing stuff. You should find it at any auto parts store. Good luck.

It has always worked for me.

You'all beat me to it. I agree! Good Stuff!

Hey, Scott,

Techno,
There is something just for that. Jeffco 9700. It is the some thing I'm going to use on the fuil tanks for the aircraft I'm working on. You should find it at aircraft Spruce.

JB weld is definitely fuel proof.

JB weld,

I 've used it for years on fuel tanks and patching holes on my blocks. I've even used it inside my block to take up space where the oil injection pump gear was...............Uncle Tony

JB Weld, 2 varieties , fast cure and regular. For permant repairs, I prefer the regular. :cool:

Techno,

There really isn't any epoxy that is fuel proof long term. What are you trying to do?

If you just want to "seal" your tank, my company makes a sealant for aircraft wing tank sealing. It a polysulphide two component product used by the airforce, Boeing and others. Available two ways - brushable or paste.

They didn't come out and say for fuel on the aircraft site, I may have missed it. On the other site they did. http://www.fgci.com/
3:1 LAMINATING EPOXY

3:1 Epoxy System is designed as a blister barrier and provides excellent chemical resistant properties. Our 3:1 Epoxy System can be used to repair fuel tanks, pipes and as tank linings for certain chemical environments. The 3:1 Epoxy System is also D.O.T non-corrosive.

I want to build my tank as the one I bought sucks, or rather pumps. It pumps gas out of the vent on a hot day so I lose the top 2 gallons or so. I also can't suck the last 2 gallons or so of gas if I'm on plane so my 20 gallon tank is under 16 gallons.
I also want more gas so I'm making it around 34 gallons.
I went once, 24 m in 23 minutes average speed 63 top 92 and sucked about 8 gallons(eyeball). If I traveled the same route at 100+ I'm not only low on fuel but this isn't a very long time.

I can either lam it from fuel proof epoxy or coat it, I just don't want a surprise later on. THe plan is to use klegecell foam. It will fit the space with a few extra bumps for stuff, like a vent. I also need a fitting for oil injection. this isn't the engine variety but for the tank.

I'm probably better off sealing it with something permanant than the epoxy. WHats this stuff and is it pricey?

Isn't John Lanes fuel tank in the new boat all West Systems and Kevlar.

Techno,
Epoxe uses chemical reaction to create a type of plastic from 2 interactive components. This plastic is not soluble in gasoline or its additives any more than plastic fuel tanks are soluble in gas. The components that make up the hardener and the resin ARE soluble in gas until they are combined and allowed to cure, becoming a new compound. PLASTIC. I have used JB weld for years to patch things. The trick is to make sure its reinforced. I have made patches using plastic roof sealing mesh and JB weld. I fixed a car radiator this way. I would bet you could make a fuel tank this way. It will take alot of epoxe but will work fine. If you must have epoxe that is gauranteed to be impervious to fuel, get "fuel tank patch". Its available at almost any auto parts store. How about making a tank from fiberglass?

Good luck dude.
