Most vehicle repair shops are encountering a lot of fuel-line-related issues since the introduction of ethanol into America's pump gas. Because of ethanol's effects on rubber, plastic and metals, they are finding themselves spending a lot more time fixing fuel delivery systems than they did in the days of leaded gas and carburetors.

Shops that perform these fuel system repairs are faced with the fact that there are now many possible types of fuel line that are necessary to make a proper, safe and durable repair. The few rolls of neoprene fuel line or steel tubing that used to hang on the wall are now only part of the varied products needed to perform these repairs. New sizes, new materials, new attachment fittings and new manufacturer's O.E. recommendations have caused many shops to expand their inventories of fuel line products to meet market demands.
