Alright so i picked up a 79 rx7 and stripped it to stock car for a local leauge (sorry it was a rust bucket) in the rules they stat no fuel tanks under the car behind the rear axle. So that means im relocating. Now the rules allow a 25L (6gal) boat fuel tank to be used as a fuel cel. So i found a old cheap tank on a local classified site. But its only a "single line" tank. Now i havnt gotten under to look at how the fuel pump and gas tank are all ran. And cant get under it again till next weekend at the shop. So my questiom is should i pick up this tank. Its supper cheap on the classifieds.
