Is that some new NHRA rule of just the manufacturer's experience? I ask because I am using the 5 gal alum tank that was in my fish and bolting it to the back-halved Demon using the 4 tabs they have welded to it. Sorry, no pics but I like this thread.
The 10 gal fuel cell I bought had the note in mentioning about no longer having the tabs.I,ll have to look into the NHRA rules and get back with an answer.
