I'm not argueing, but just trying to get a better understanding for myself. This is straight from current East Coast rule book.......
FUEL SYSTEMS
1. All fuel tanks, pumps and fuel lines must be located
outside the driver’s compartment. Front mounted fuel
tanks permitted but must be located behind front axle and
inside body. All fuel tanks must be protected from
collision. Any fuel system components located above the
floor (excluding the fuel tank) must be enclosed.
Maximum one (1) quart capacity tank for nitrous
enrichment systems. Tank must be mounted out of header
area. Front mounted fuel tanks permitted, but must be SFI
rated fuel cell, and must be located behind front axle and
inside body.
2. Nitrous oxide bottles and/or pressurized bottles used for
shifting transmissions must be labeled as to content and
securely fastened within the confines of the cage to
protect the bottle from damage in all reasonable
circumstances. Shut-off valve must be within reach of the
driver while he/she is harnessed in the seat.
3. When driver is not claiming Nitrous Oxide, the line must
be disconnected from the inlet side of the nitrous solenoid.
4. Spare gas cans are not permitted.
5. All cable type fuel systems shut offs, recommended pull
to the off position.
6. Carburetor must have a flash shield or an air cleaner.

7. All relocated fuel tanks must be vented lower than the
bottom of the tank. No vented caps permitted. All fuel
cells exempt from outside vent. Any additional vents must
be self-closing type.
8. Mandatory two (2) throttle return springs.
9. All fuel cells must be SFI approved.
10. Rubber pressurized fuel lines are limited to max length of
six (6) inch segments. Fuel injection systems exempted.
11. Three (3) classes of fuel permitted: pump gas, racing fuel
and alcohol.
a. Gasoline - any fuel with sp. gravity .792 and lower at
70 degrees F
12. 10% of cubic inch for all performance additives added to
fuel.
Nowhere does it state hard or braided lines. #10 says that rubber "pressurized fuel lines" are limited to 6" max. If it gravity fed to the pump, that's not pressurized. I'll carry the rule book with me to tech.
Am I correct or not?
