I'm going away this weekend & my sub tank light is on. I put a big dent in the bottom of my tank recently but everything still worked.

Against my better judgement, we tried blocking the breather off & pressurizing the tank with air while it was still in the car to pop the dents out. It didn't work as well as we wanted so we pulled the tank out & did the same thing & tried beating the dent out from inside. However when I put it all back together my sub tank no longer switched on & shortly after the sub tank light on my dash came on & stays on.

My question is, what could we have damaged by pressurizing the fuel system so much? Or is it more likely to be electrical & if so, what? I'm flat out at work so don't have time to diagnose it myself so I'm hoping there's a simple answer.
