What size fuel tank ?

Converting from flathead to clone, what size fuel tank do I need ? Will 2 1/2 qt work ? Little pushed for space on an older chassis.

You should be fine with a 2 1/2 qt tank as long as you dont have a lot of cautions in a 20-25 lap race.

2 1/2 qt tank works fine for me with a clone motor even in a 50 lap race with several cautions

Will the 4 qt fit? If not 2 1/2 qt will last you plenty

I seen a few karters with the 4 qt on their clone engines.

Yes I have a 3 quart and fill before I leave home and don't even bring gas with .
pretty risky. of course you could always beg or borrow fuel if some unexpected thing happened.
Just a thought, get the biggest you can fit, because you might be able to use the extra capacity to add more fuel to make weight if their scales are a few pounds light.


We took the 2 qrt tanks on our box stock class and ran 100 laps few cautions too but they made it. Barley but they did it I was surprised
