Correct.
Ollie did develop the tank yes for RHD, but to be fair these were already available in the US albeit LHD. The theory behind them was already proven but as always over here we are a couple of years behind and our weather is not quite as warm so the demand is less. In the US these tanks are circa $450 and are finished better aesthetically.
I work in Engineering and have developed parts in the past (from scratch) and people still copy them, unless you patent them then that's life.
This is a metal tank, of which I'd like to make one for my own car but more in keeping with the design under the engine bay, I want it to look the part and maybe incorporate additional insulation. Getting hold of one second hand means I don't have to give up my car for a few days, but if that's what it takes then that's what I may do. As for stealing Ollie's market on these then I don't think so.....
I stand corrected on the price it is £550 for the tank, still a reasonable budget for me to do my own.
I am one of the most open forum members on here when it comes to sharing modifications, information on the 55k and testing.
