Echo 2511T fuel tank repair

[4CornersPuddle]

I have a crack and fuel leak at the base of the support post for the brake flag on one of my 2511s. The saw was dropped from "way up there" resulting in several damages. It is the flywheel side. Replacing the entire tank is way down on the list for me.
A slight bit of flexing can open the 3/8" long curved crack maybe 1/32".How might I go about sealing this? What adhesive might seep in there and stand up to contact with fuel and also resist the small bit of side pressure that setting the chain brake requires? Some degree of runniness is necessary; the viscosity of typical epoxys would be too great.
Thanks for your help.

Use the tip of a solder gun to plastic weld it after applying a vacuum to the tank.
How much do you use the chain brake?

Superglue (crazy glue) is fuel resistant, I have repaired plastic tanks a number of times using it.

Super glue it shut clean off any excess glue when dry and then get the same plastic to drip seal/patch it.
What this is, is basically lighting on fire the plastic and letting it drip onto the crack. Do not touch it to the tank while dripping or you will get strings of plastic or worse the plastic of the tank will melt from too much heat. The plastic will melt into the surface of the saw and seal But it has to be the same plastic as the tank.
And OBVIOUSLY drain the tank and give it a swish out cleaning with denatured alcohol or rubbing alcohol & time to air out before sealing.
