Re: Fuel Filter Replacement interval for 14' Grand Cherokee
I don't know hard it is, but I don't think it is something you need to worry about. Assuming you are referencing the gas (vs diesel) version, according to WK2Jeeps:
"Two fuel filters are used. One is located at the bottom of the fuel pump module, the other is located inside the module. A separate frame mounted fuel filter is not used with any gasoline engine. They do not require normal scheduled maintenance. Filters should only be replaced if a diagnostic procedure indicates to do so."
