Fuel tank damage?

Asked by COSK2 Sep 12, 2018 at 02:26 PM about the 2010 Ford F-150 STX SuperCab 4WD

Question type: Maintenance & Repair

Some thief siphoned fuel from my 2010 F150 a few months ago and ever since,
I've been getting horrible gas mileage.  I'm wondering if something could have
been damaged by putting a tube down the filler tube into the tank or if the
locking gas cap I installed could impact miles per gallon.  Thank you!

They may have damaged the anti siphon device but that would have no bearing on your fuel economy. Is the check engine light on? Do you have a gas leak?

Thank you - The check engine light was on briefly after the first two or three starts after the theft. No gas leak.
