Disconnecting FP oil switch

Would there be any negative side effects to disconnecting the harness that powers the fuel pump via the oil pressure switch at the back of the block?

I want to install a sending unit for my aftermarket oil pressure gauge however the port at the front of the block does not have enough clearance.

I am under the impression that the only problem that could arise from disconnecting this switch is I would be stranded in the event of a FP relay failure. Someone correct me if I'm wrong.

Won't help if you loose the control (ECM ) side of the relay.
Seems to be a common complaint with age

Leave the switch plug accessible and carry a jumper so you can hot wire the OP switch
so you can run the pump to get home
