P0457 Ford - 2010 Escape, will an optional locking gas cap provide a better fuel filler seal?

Question

Get intermittent "Check Fuel Filler inlet" message on dash, and/or MIL with P0455, P0457 OBD2 codes.

Was told the Fuel Filler Inlet needed to be replaced, $300-400.
Seems high for what in my opinion is a poorly designed capping system.

Wondering if a lower cost solution exist, such as an after market locking gas cap?

Answer 1

Hi there,

The car needs to be smoke tested for leaks. If this has been done and the filler tube is the problem then a gas cap of any sort isn't going to solve the problem. You could try looking for a used fill tube to save some money.
