what kind of bladder are you planning on using? Most dedicated fuel bladders I have used, while in the military, are very thick. By the time you stuffed it all in there.. and lost all the space to the wild corners and nooks and crannies I wouldnt think there would be much room left for fuel. I like the idea of using POR15 to coat and seal the inside of the OEM subframe.. but I am not sure that POR 15 or other normal gas tank coatings will stick to plastic tanks?? I know Red-Kote wont.
We are enmeshed in the cancerous discipline of "security." And in the worship of security we fling our lives beneath the wheels of routine - and before we know it our lives are gone.
