. Much obliged for the help.I have a 20 gallon fuel cell from Jegs in my car. It's an aluminium one with foam in it to keep the sloshing to a minimum. My gas gauge doesn't work because at the time (7 years ago) they did not make a sending unit for it. I have the vent line running though the big hole where the filler neck used to be. The only issue i've had is if the tank is full and I do some high g force action (drag racing, donuts,etc) fuel will come out of the vent line. The cell had to be turned sideways to fit in the trunk, and to clear the hump in the middle of the trunk I made some 3 inch spacers to raise it off the trunck floor. It barely fits.Alright, for those out there that have been more performance minded, or even just safety minded, who has installed a fuel cell in their 71-73? What brand, how many gallons did it hold, amount of modification needed, ya'll know the drill
Check out his "garage" I think I remember seeing them there
