You may try an external fuel pump but it may not correct, or help with your problem. Dropping the tank to change the internal fuel pump is not a fun job but like many things, there is a right way and a wrong way.
Along with your internal fuel pump you have an internal fuel filter/strainer. Considering the age of your vehicle, it ran for quite a few years with a minimal amount of ethanol blend fuel. The new fuel does a better job of cleaning out your tank, and a lot of that debris is caught in your in tank filter/strainer. This accumulation of crud may restrict your pump inlet from time to time and cause your fuel pump to overheat. Installing an external fuel pump, and using the same fuel lines means that you will be sucking fuel right through what may already be a partially blocked filter/strainer inside the tank. This restriction may actually burn up your new external fuel pump that is not sitting in fuel that has helped to cool the in tank pump.
Just saying if it was as easy as simply installing an external fuel pump, NOBODY would ever replace their in tank fuel pump.
