Fuel tank issue

[PEJ5]

The return fuel line connection on the top of the fuel tank broke off on my DK5010. It went from dripping fuel to spewing fuel within 5 minutes. As for how - I am guessing the barbed connector was stressed last year when the tractor was split. I can see the return line and hose clamp laying on top of the fuel tank with the broken connector inside the line.
I am looking for advice from anyone who has removed their fuel tank or done related work. I am hoping to be able to repair the tank return connection. I am thinking that I can tap in a new barbed connection on top of the tank. Is the tank removal process straight forward? Does the return fuel just dump into the tank so I can dump it in via a new hole/spigot if I have to reposition the hole location, or is there something inside the tank such as a tube to the bottom? Do I have to invest in a new tank?

Feedback and tips appreciated.

Heck, I'd simply drill a hole near the tank top and insert the return hose and seal as best you can.
Use a magnet to catch metal chips as U drill.
You could also solder (hot iron, not a flame) a flange fitting for a more permanent and professional job, also sealant and pop rivets could be another option.
Heck epoxy could 'glue' a flange suitably as well.

I use epoxy for many things, and this would likely be another situation where I would use it.

Peter - I don't know about your Kioti. Mine heads back towards the fuel tank starting with a short steel line. It then turns into a nylon braid reinforced rubber line. At the fuel tank there is a 90 degree elbow. The rubber line ties into the elbow and is held tight with a hose clamp.

This is all well and good in my case. If I stand on my head and look thru my left arm pit - I can actually see it. Not even a piss ant could reach it though. I would have to drain and drop the tank.

Unless this elbow were broken off - flush with the top of the tank - imagination, more rubber hoses, bits of straight pipe - hose clamps - it's repaired.

Thanks for the assistance. My tank is plastic so epoxy should work well. Oosik, thanks for observing that the connection is an elbow vs a vertical connector. There may be enough left to work with. It sure is a tight space so I am faced with removing the tank to complete the repairs which will result in having to bleed air out of the fuel system. Hopefully that is not too difficult a task.
I would welcome comments from others who have tackled tank related work.

I have tractor work/chores backed up so I'll have to get at it.

"Epoxy" covers many products not all well suited for a plastic tank or diesel fuel.

Thanks for that advice. What should I use? Maybe JB Weld? It claims to work on plastic and I think it is fuel resistant.

Find out what the tank is made of. Abs, Pvc, PP, PE. And plastic weld it. I have repaired many tanks this way. I use a portasol butane soldering iron with a hot knife attachment. Melt the substrate then feed rod into it.
Plastic welding rods can be bought on e-bay. You get about 20 rods of each type of plastic.

The return hose was incorrectly wrapped around the floor/deck mount which put undue pressure on it. Oh well, time to repair.
There is a bit of tube on the tank but not enough to clamp to. See photos. I do not want to wait for special plastic welders. I am thinking of Seal All. I will glue the piece on and then build it up with a thin coat. The hose clamp should hold it in place. There is no pressure on the hose and the fitting other than me pressing on the hose once.
I have a brass fitting, but I'd have to drill a fairly large hole and get it just right for the threads to bite. I think this would be plan B.

Suggestions?
