so if you install a fuel cell into the bed of your truck what are the requirements for nhra and ihra? can we put it near the tail gate behind the rear axle? do we have to add any bracing to the rear of the bed if we mount it back there?

 

Good question. I think I heard that it had to be at least half way below the floor of the bed to be legal but I could be wrong.

 

where might i find n instruction on this?

 

maybe try there website maybe they have a guide in pdf form.

 

i'll take a look.

 

any luck?

 

i'll look today if i get the time here at work.

 

COMPLETE IHRA Fuel System rules {reprint}
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. Fuel-pressure-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 chrome moly or .118 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 data-recorder
lines) must be metallic, steel-braided or IHRA-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. IHRA-accepted woven or woven-pushlock
