I am pretty sure that FC were forced to warranty the exterior fuel relay for around five years .The trouble is this is a cheap fix as other original relays in the TIPM can play up as well.I will see if I can find the info. Remember this was a world wide safety recall forced on FC.
Found info,FC in states has to warranty the new exterior relay for 7 years or 70000 miles by law from original purchase date.What the heck did the dealer charge you $800.00 dollars for.?What does their receipt state.? Also there is a company in the states who has various fixes for this problem .Google
