Anyone,
The Escape has three (3) possible types of fuel pump systems: fuel-return type; mechanical fuel returnless type; electronic fuel returnless type. It’s up to the question poster to look, or have some to look, and determine which type of fuel pump system is on their Escape (or, other Ford). The answers to the questions, about finding the causes of the problem the questioner has, is dependent upon having this information.
