RedKote is bunk. It, like Kreem and POR-15, is ethanol based. Ethanol creates the catalyst for gardening, therefore ethanol bases will always soften them.

Caswell is the way.

I'm saying that if I were you:

Apply lining of Caswell on edge of plastic, push together, and than line it heavy.

It will be a single piece for eternity.

Or, just source a metal Solex tank and leave the chemicals for huffing.

I can attest to this stuff, it’s been holding my plastic fuel tank together 2 years now.

It's $32, or you can just muckle it up trying some random chemicals you find in the garage.

^^^thanks for the offers,

So after testing the super glue dimples in gas for a couple of hours its still hard and dont scratch off... So i squeezed a tube and a half into the side with the well and held them together. Bam superglue everywhere. Time will tell or hopefully Monsuier Solex will chime in. Cyanoacetate is underated.

My 1980 FA is the only year to have the elusive side of tank fuel level gauge. The threaded insert (O.D. about the size of a jockey puck) is molded into the side of the tank and cracked at the factory seam. I rotozipped the entire thing out and glued it back in. So yeah, always in contack with fuel.

I bought one of those Hungarian Solexes they were selling back in the early 2000s. Brian believes it may be one of the last ones. Not long after I got it the gas tank started leaking. It turned out to be cracked where the gas line fitting screws into it. The place where I bought it sent me a new one.

"Cyanoacetate is underated" Super glue is actually Cyanoacrlate. It was originally developed as a liquid bandage for battlefield use during the Vietnam war.

Great post...please keep us updated.

Gerald, your Solex was definitely in the last container of Solexes that was shipped over here.

There used to be a sealer called Sealer 1000 used in the marine business. I think it has been discontinued but it had a dark reddish brown color and was gas resistant.Omc marine specified using it to seal the halves of outboard lower units.

No single part adhesive will hold up to gas. I have tried a bunch and no go. (edited)

Thanks for the update...and nice score on that tank!

This might seem an odd idea but I’ve done it to many weed wacker cracked plastic tanks to repair. It’s generally ugly but I’ve never had a leak after.

I use a soldering iron on plastic tanks that are cracked. Remelts the original plastic and seals cracks. If there’s extra plastic on the edge the tank doesn’t need, I’ll scrape it off and add it to the cracked area.

In the case of a 2 part tank like this maybe focused hot air or small low propane torch could do the same thing to melt the parts together

i love that the best solution is superglue. hell yea
