Had something similar happen to mine. There should be a form that you can complete to file your WIF complaint with the main corporate office. If you have comprehensive coverage on your truck, you can file a claim on your insurance. Submit to them a copy of the compliant form, receipt for diesel fuel that caused the issue, and Ford repair invoice. They will typically pay the claim and then pursue the station. If you don't have comprehensive coverage, your only alternative is to find an attorney to pursue the issue. It is a long and difficult process that way with no guaranteed resolution.
