Are fuel tank sumps ok for NHRA rules?

[lmccoll]

Does anyone know if fuel tank sumps are ok for OEM has tanks per NHRA rules? Seems like I read once in NHRA rules that any OEM tank has to be unaltered, but now I can't spot that rule in the rule book. Anyone know the answer to that question?

Thanks for your help, Larry

Hi, no, I know of no rule for unaltered stock fuel tanks.... maybe in the stock class...
moroso, or comp engineering makes a sump you can install on any stock tank, ......but get a gas tank repair shop to install it for you.... gas fumes and sparks or flame tend to cause the air inside the tank to expand very rapidly.... :shock:
It may be more cost effective to just install a fuel cell, they are a little safer and look nicer.... summit sells some nice aluminum cells at a decent price.

Thanks for the info. I might have read that in a stock class rules sometime, I couldn't find that rule recently though.
