Rear engine broken fuel inj line

Two weeks ago on a bfr flight my rear engine began running rough and the egt began to climb at a rate of 25 degrees per second. We were close to the airport so I powered back the rear engine to lower the egt temp and proceeded to land without incident. Once on the ground we did a runup and the rear engine was running very rough and still the egt temps would increase at 1800 rpm.

This flight could have had a very different outcome based on what the shop found to be the problem. It was a fuel injection line broke completly off at the injector spraying fuel in the engine compartment. We were very lucky this time.

My question is would one broken line reduce fuel flow to the other cylinders creating a lean mixture causing the egt to increase?

Any other ideas what might make the egt increase?
