Fuel cell leak

Make sure the top has a vent open with a line out the trunk floor. If it has a rollover valve, it may be stuck closed.

yea that's the crazy part about it, i had no vent line installed when i noticed it collapsed. ( i have fuel in it but have'nt raced it yet.)

Other wise thanks, I have no idea if it has a rollover valve in the vent. but i'll look tomorrow.
