FUEL TANK
The Monforton book on page 2.31 lists the location and size of the fuel intake in the fuselage along with the two breather holes. I tried to simulate the size and shape with the existing fuel dots that are available. As this is a Sports Scale version, I'm not worried that the fuel dot is a 1/32 inch too big.
Thunderbolt RC sells a new Seacraft fuel bottle holder that worked very well for my situation. I was able to shape it to the fuselage shape and I held it in place with Hysol 9462 Epoxy. It will never move!
The mounts only weigh 32 grams.

I was able to put the fuel tank exactly over the CG for this airplane, so I should have no trouble with the trim as the fuel is used up. I'm using a 50cc tank for the 77cc 4 Stroke engine, but if I need more it is easy to add a Pepsi 710cc tank.
I personally like using the quick disconnects from Thunderbolt, it makes it very easy to remove the tank in seconds. The one on the line to the engine even has a quick shut off so if there is any tank it won't leak out.
