996 Reawakened after 5 years

[CogitoErgoZoom]

I'm in the process of bringing my 996 race car back to life after essentially being in storage in its enclosed trailer for the last 5 years. I did a race in March 2020 on the weekend the pandemic lockdowns were declared, the car got parked with the fuel that was in it, then life got in the way and there it essentially sat until now.

I moved late last year and had no choice but to start the car a few times to move it, but I did manage to change the oil before that. I'm now in the process of bringing the car fully back to track ready. My plan is to drain the fuel, inspect the tank for any residue or debris, fill it with fresh ethanol-free fuel & Techron, change the fuel filter, and see how it's running before changing the oil again.

I started to remove the fuel level sender and pump assembly and promptly snapped the nipple off what I'm assuming is the tank vapor vent port. I removed the charcoal/EVAP a long time ago, so I'm assuming that's not going to be a problem. I know it's not ideal having it vent directly under the battery. I know the smart thing while I'm there is just to replace the fuel level sender and fuel pump given that both are 25 years old at this point.

Any other suggestions? Removing the fuel rails and injectors before/after for cleaning or overkill?
