NASCAR said "HEY you can't do that!" He said it was not in the rules
The next week they had a rule that the fuel line could only be X number of feet.
Smokey then proceeded to use that X length of radiator hose for his fuel line with reducers at either end, and it gave him even more extra fuel LOL
NASCAR rules now cover every tiny detail of the cars and the racing sucks.
Hey! It’s legal!.......................
