The fuel tank looks like the simplest thing, and it is. The temptation is to use a regular, rectangular shape can, something from a motorbike or mower. The important thing is to avoid possible surge leading to no fuel pick-up and the possiblity of stalling. A long shape like this works really well, and fits anywhere. Holds about 4 litres.

Ordinary sewer fittings work well. Follow the directions using the proper primer & adhesive. I tested this by leaving the components in Avgas & petrol for a few days. To date there has been no sign of leaks, fractures or any other degradation for three years. Prior to that I used Galvanised downpipe but they tended to rust after a while.

The clear line is the regulation vent, set up so that if the car tips over, fuel doesn't run out. Cap is non-vented.
