Stocker Tech Rules Gas Tank & Battery?
If you use a stock mounted battery location are you allowed to modify the tray and hold down to prevent the battery from tipping or moving around? Lastly if you use a stock tank can you modify it too for a sump and smaller actual tank capacity? If not can you use it to cover the bottom half of the fuel cell so it still looks stock from behind and underneath? Thanks in advance for the input.

Yes to battery mounting. In fact you need 3/8 metal holddowns and to replacethe open J hooks that are usually the factory mounting. I have never heard of the gas tank sumps being illegal.....but why not have the safety of a fuel cell instead of all that work on stock tank?

Re: Stocker Tech Rules Gas Tank & Battery?
NHRA 2015 Rule book under Stock
GAS TANK Must be correct year, make, and model for car used, with stock fuel inlet and outlet locations. Must be in stock location; fuel line and pickup may be resized. Fuel cell permitted; maximum capacity 16 gallons. If fuel cell is used, OEM gas tank must be removed, and a firewall of minimum .032-inch aluminum or .024-inch steel must be installed to totally seal driver compartment from fuel cell. Trunk floor may be modified to accommodate fuel-cell sump. Where OEM gas tank is in the trunk floor, area occupied by OEM tank may be replaced with material equal to or heavier than OEM floor. If OEM gas tank is used, it must remain unaltered.

Re: Stocker Tech Rules Gas Tank & Battery?
Based on the rule, he could probably use the material from the bottom of the OEM fuel tank to fill the hole vacated by replacing it with the fuel cell. Use the bottom of the tank as the "equal or greater thickness" fill material. This is Call the Tech stuff, though.

Re: Stocker Tech Rules Gas Tank & Battery?
the way I read the rule is if using a stock tank you are only allowed 2 MODIFICATIONS to the tank you can RESIZE the fuel line & the pickup--- it says nothing about sump areas in a stock tank being allowed that I would consider a modification--- NO OTHER MODS ALLOWED--- now if you use a fuel cell many times a sump area will be molded in as part of the design so you will be OK and in addition you must fabricate a metal barrier between the cell and the passenger area---my take on it-- FED387

Gas tank shields were used as far back as the 60's..sometimes as a good way to add weight (C/FX cars, etc.) I don't see any good reason why you couldn't fab one out of a gutted oem tank, and securely mount it to shield the bottom of the fuel cell and it's fuel lines. Of course if you ask ,rather than just doing it, I'm sure the answer would be no.

On a car where the factory gas tank is the trunk floor, do they require you to install a metal barrier? |
