Anyone have any Tech issues with Fuel Return Systems
I just put in my CJM return system and this was brought to my attention
section 1.5 of the 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) 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.
anyone have a problem with passing tech at NHRA sanctioned events, i attend some and i am sort of worried, there really isnt a good way to mount the FPR besides the firewall

i think i might be misinterpreting but i saw this
"fuel-distribution blocks, etc. must be
located at least 6 inches forward of the flywheel/bellhousing area
on rear-wheel-drive (RWD) cars,"
and i figured the FPR would be considered a distribution block

the fuel rails are distribution blocks.
