Question:

I’m installing a new fuel cell in the trunk of my Pro ET car.  If I use an aluminum fuel cell will I still need to run a ground wire to it?

Answer:

Per the 2019 NHRA Rulebook in the General Regulations section 21, page 4, 1:5 Fuel Systems, Tanks: the last sentence states “Nonmetallic fuel cells or tanks must be grounded to frame”.  So to answer your question, an aluminum fuel cell is automatically grounded by mounting it to the frame and in turn no additional ground wire is required.
