as per nhra rulebook...
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) vehicles, and on opposite side of flywheel/housing area on front-wheel-drive (FWD) vehicles. Fuel pressure gauge isolators, with steel braided line, may be mounted on firewall

i have often wondered why a firewall mount was prohibited. i would think if mounted on the inner fender, and a crash into the wall tore off the fender and inner structure, the firewall mount would be safer.

Their main concern is a clutch or trans explosion which could take it out

Your fuel line must also be routed outside the frame rail, or be run through a length of pipe in the bell housing area to shield it.
Don't think that is called for as long as it is a steel braided line.
Correct. SS braided line would be fine in that area.
FWIW, my reg is mounted to my fender about 6"s forward of the firewall. The anal retentive tech insp said he felt it should be farther forward still as the forward edge of the bell housing was forward of the firewall and their fore my reg was within the 6" zone.
So, I've gotta move my reg forward about an inch.

Lines: All non-OEM fuel lines (including gauge and/or data recorder 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 and motorcycle 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. It is mandatory that fuel lines passing supercharger drive belts be steel braided, NHRA-accepted woven or woven-pushlock, or be enclosed in protective steel tubing. A current list of NHRA-accepted woven or woven-pushlock fuel lines is available on NHRA.com. All NHRA-accepted fuel lines must use ends that are specifically designed for the type of fuel line being used. No hose clamps allowed on NHRA-accepted fuel lines.
