I was told by an NHRA tech that you cannot have the fuel cell nor fuel pump mounted on the firewall. Also was told none of the fuel lines can run over the tranny case. I did notice alot of people running the fuel cell on the fire wall and there fuel pump as well.. So what can you do? I put everything of mine in front of the drivers tire which ended up being a pain in the ***.

 

i put mine in front of the trans, but not directly in front of the flywheel/bellhousing.

 

And post up some pics if you got em.

 

 

From what I understand you can not have it mounted on the firewall itself. But I think you can have it where the battery box was since that isnt mounted directly to the firewall.

Quick question. What if your firewall was cut. Mine was cut when I got the car. I remade the firewall, and I am re-enforcing the back, inside the cabin and welding it all shut again.

I have the fuel cell attached to it, but it is on the outside layer. I am kinda in a tough situation with it.

 

i would like to kmow also. one of the fuel cell bolts goes into the firewall and the other goes on the strut tower. also i bolted the fuel pump to the firewall opposite the tranny.

 

i read the 2007 nhra rules and it says nothing about not being able to mount the fuel cell or pump on the firewall. it did mention that the firewall had to be sealed as to prevent fuel from entering the inside of the car. someone double check me though.

1:5 FUEL SYSTEMS

Location:

All fuel tanks, lines, pumps, valves, etc. must be outside
of the driver’s compartment and within the confines of the frame
and/or steel body. Cool cans, fuel-distribution blocks, etc. must be
located at least 6 inches forward of the flywheel/bellhousing area
on rear-wheel-drive (RWD) cars, and on opposite side of
flywheel/bellhousing area on front-wheel-drive (FWD) cars. Fuelpressure-
gauge isolators, with steel-braided line, may be mounted
on firewall.

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.

Lines:

All non-OEM fuel lines (including gauge and/or datarecorder
lines) must be metallic, steel-braided or NHRA-accepted
“woven or woven-pushlock.” A maximum of 12 inches total (front to
rear) of non-metallic or non-steel-braided hose is permitted for
connection purposes only; individual injector-nozzle fuel lines are
excluded. Fuel lines (except steel-braided lines) in the
flywheel/bellhousing area must be enclosed in a 16-inch length of
steel tubing, 1/8-inch-minimum wall thickness, securely mounted
as a protection against fuel-line rupture. Fuel lines may not be
routed in the driveshaft tunnel. NHRA-accepted woven or wovenpushlock
fuel lines: Aeroquip FC300, FC332; Aeroquip Star Lite
200; AQP Socketless; Dayco Imperial Nylo-seal tubing; Earl’s
Prolite; Fragola Performance System Series 8000 Push-Lite Race
Hose; Gates LOL Plus; Goodridge 526; Goodridge 710; Russell
Twist-Loc 836 and XRP HS-79. Contact NHRA for updates.


Pumps/Valves:

Cars with non-OEM-type mechanical fuel pumps
must have a quick-action fuel-shutoff valve within easy reach of
driver and be located in the main fuel line between the fuel tank
and the carburetor and/or injectors. Fuel-recirculation systems not
part of normal fuel/pump system prohibited.

Fuel/Air:

Any method of artificially cooling or heating fuel
prohibited, except for cool cans.Wet towels, rags, ice, etc. must be
removed before vehicle leaves staging area. Intercoolers may be
cooled with nitrous oxide or freon. Liquid intercooler tanks limited
to maximum 3-gallon capacity, may use water/ice ONLY. If located
in driver compartment, must be securely mounted to frame or
frame structure.

Alternative Fuels:

Containers for alternative fuels must be
permanently labeled by the manufacturer as suitable for CNG or
propane. Tank must be vented outside of body. Alternative fuel
systems must incorporate pressure-relief valve meeting standards
listed in NFPA 52. Alternative fuel systems must incorporate a
manual shutoff valve according to standards listed in NFPA 52 for
CNG vehicular systems. All hoses/lines used for alternative fuels
must be permanently and distinctively marked by the manufacturer
as to manufacturer name or trademark, service identifier, and
design pressure. Plastic, cast-iron, galvanized, copper, or
aluminum pipe or hoses prohibited.

 

Its sad and stupid that I cant put my fuel cell like on the pic. In Poland it is allowed to mount the fuel cells only behind the driver behind firewall...
