Question:

I’m finishing up a 10-second E.T. Snowmobile that I will be running at my local NHRA track in Super Pro Bike.  Is it legal to use the original oil injection tank as a fuel tank?

Answer:

Yes it is.  In the 2019 NHRA Rulebook section 4E  E. T. Snowmobile, page 18, chassis: 4, fuel tank, it states “Oil injection tank may be used as a fuel tank.”
