Hello everyone, I recently had a mobile mechanic, come out and diagnose My 2007. Dodge caravan as needing a new fuel pump. I’m getting it repaired today at a mechanic shop. And the guy said “just so you know if the new fuel pump doesn’t get the car running. You still owe us for the repair job”.

This is throwing off alarm bells that they may try to scam me and not actually replace the fuel pump… Is there any way for me to tell if they have actually replaced the fuel pump? Anything I can look for that might indicate its a new pump or that its actually been replaced?
