Do trunk vehicles need an added metal bulkhead added to them if they have a fuel cell mounted in the trunk? Even if they have all factory seats and bulkhead in position?
I came to a bigger site to get more input. Nothing wrong with that is there?Yes, rear seat is not the ideal bulkhead.
Read the rule book.
You got same answers from other site, are you looking for different answers or you simply don't want to install bulkhead per NHRA spec?
Tanks:When permitted by class regulations, fuel tanks located
outside body and/or frame must be enclosed in a steel tube frame
constructed of minimum 1 1/4-inch O.D. x .065-inch chrome moly
or .118-inch mild-steel tubing. All fuel tanks must be isolated from
the driver’s compartment by a firewall, completely sealed to
prevent any fuel from entering the driver’s compartment. All fuel
tanks must have a pressure cap and be vented outside of car
body. A positive-locking screw-on fuel-tank cap is mandatory on all
cars. Insulated fuel tanks prohibited. When used, fuel cells must
have a metal box protecting the part of the fuel cell that is outside
of body lines or trunk floor, excluding hose-connection area in rear.
Non-metallic fuel cells or tanks must be grounded to frame.
No not really, but it certainly seem like you want to hear different answers.I came to a bigger site to get more input. Nothing wrong with that is there?
LOL...more than 2 different people just gave you true answer and you're still not satisfy.Does anyone have a link to the rule book online because i am yet to get a true answer just what people think the answer is so far..
..
I got their opinoin no real answers yet until i found the rule book online and it is still a grey erea it seems.. .
As for people that have done it a long time yu have no clue how long i have been racing.. It is comments like that that make people ask others because you are an ASSumer...wow, that is kind of insulting.
It seem like you don't trust real racer(s) who've done this in a long time.
YBBitch:
Grey area....gimme a break...:roll:
You mean vinyl isn't a good isolator?You found the rule and it's not confusing. There is another rule about the same bulkhead being required if the battery is in the trunk. Just because some tech guy didn't bust you in the past doesn't mean much. All you need is a sheet of .024 steel or .032 aluminium behind the seat and under the speaker deck. All fuel tanks must be isolated from
the driver’s compartment by a firewall, completely sealed to
prevent any fuel from entering the driver’s compartment.
Apparently it has been good enough for one guy anyway......LOL.You mean vinyl isn't a good isolator?![]()

Thanks for the help though..![]()
How about fire suit? :smt115Shit, that solves it... I'm saving weight now. All steel panels are getting replaced by this new fangled fuel/fire proof vinyl.
Where might I buy such a space age material?
Pathetic is someone following someone around the internet forums over tech questions.. :smt039LMAO...very funny...if you "claim" you're a racer or have been racing for awhile then you should know the rules or purchase rule book.
How pathetic...![]()
A Fire Blanket behind the factory seat on the inside might not be a bad idea..
Firewall must provide amagnesium prohibited.
bulkhead between the engine and/or fuel tank and driver
compartment. All openings must be sealed with aluminum or steel.
In certain instances, fiberglass, carbon fiber, or other composites
may be used. See Class Requirements or consult NHRA. Use of
