Fuel pump modules will assist you in retrofitting an internal fuel pump into your original gas tank. These kits have almost everything (other than the fuel pump) needed to install an internal fuel pump into nearly any tank. fuel pump modules feature a reservoir tray that eliminates the fuel pump starvation that is common with non-baffled tanks. A properly installed internal fuel pump will eliminate issues common to external fuel pumps such as vapor lock and cavitation. Upgrade your fuel system to an in-tank that's capable of running carburetors or fuel injection with fuel pump modules.
