Issues starting after fueling

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. Well, unfortunately we can't tell you what to purchase or not purchase - having not seen your vehicle and evaluated it. It's all guesswork, and I appreciate you're operating off of advice instead of inspection and diagnostic testing -- but the fact remains that this is still needed before anyone could recommend anything to be replaced. The main reason I think of starting issues after fueling would be due to vapor lock - when the fuel system is not "breathing" properly. Your parts cited are possibly related, but as there are no technical service bulletins I can find related to your problem from Ford, I have a hard time suggesting you replace anything. When you say "I was told..." what does that mean? Who made the recommendations, and what is their skill? Yes, the 9D289 and 9F945 parts could play a part, but maybe, maybe not. Testing is required.
