I just read an article that Kenne Bell wrote promoting their boost a pump product, and in the article it said there are several issues with installing a Focus fuel pump, such as... 1) you need to cut the wiring harness for the pump, and solder the wires on it, which remain in the gas tank. 2) the fuel line dimensions are different. 3) and something about some tabs that need to be replaced with different sized tabs. Anyway, I was under the impression that it was a plug and play setup...
