I'm using a 32 gallon Fuel Safe MilSpec bladder and can system. HOWEVER I run a whole string of quarter miles at a time !
Don't mind me, all this c-c-c-c-cold weather has done frosted my brains and I'm bored st-st-stiff. :roll: :roll:
I run a 3 gal. on alcohol in the Malibu. I originally bought a 4 gal. but couldn't get it to fit next to the rad. frame and front fender well. If you're running gas 3 gal. will be big enough, but alcohol in the qtr. it's cutting it close, you'll probably use 1 1/2 to 2 gal. alcohol but less on gas if you drive it to the starting line and back to the pits after the run.
I'm running a 540 BBC on gas and I use 1 gal per pass. I drive it to the lanes and back to my pit. I have a 10 gal cell only because that's what was in the car when I bought it. Depends where you are putting it and how much space you have and do you need it for weight transfer. A 5 gal cell would be plenty in most cases.
