This is for a rear auxilliary tank for a rally bike. I have a plug ready (which I can change) but before I mould form it I could really do with some help in terms of joining the two halves once made. The only hole in the tank when it's joined is just a fuel filler ie it's small, so whilst I can get in there with carbon tape and a "brush on a stick" it's not ideal. Also, the external side: whilst the tank is going to be painted what would you guys suggest is the best method for an external join?
We're talking infusion here rather than pre preg so I cant use a bladder or anything like that. Could really do with some wisdom please.

Maybe a simple "shoe box" unión will work nice. Make a lowered flange on one halve. Add a good bonding filler to it and slide the other halve into the first one.
It has been used for years succesfully.
protect the second halve from the fresh filler.
Any filler could drop inside the tank. Not necesarely if the second halve is external as the laminate will "push" the fresh filler.
I love such bikes and Works. How will you do the thread for the fuel cap ?
