This can be done but it is not advisable with the tank still in the vehicle. There are many videos out there for people doing this on Grand Cherokees but I did not find any on your vehicle. The reason is, I have heard of 3 people who did this and had issues. One had a fire as they had vapor leak that they didn't know about and the sparks caused a fireball. The other 2 cut through needed components because they could not see what was just under the floor panel.
I have found that it is not that big of a deal to empty the tank and lower it with a floor jack to replace the pump.
Here is a guide that will help with replacing this:
Below is the location of the pump in the tank if you would like to try and cut the hole. Just make sure you are not using a reciprocating saw as the blade will surely cut through something like the harness. This means you need to use a cut off wheel or something that will give a shallow cut but that means sparks so be careful.
