Hello Austin, welcome to YT! I am not sure if this is possible but I wonder if compression could be getting pushed out of an injector return port. This might offer an explanation of why the hose blows off. It may also indicate that the return line is plugged back to the tank. I would say it should be open with no restrictions. If you could run the engine with hoses connected to the injector return lines and also the pump return and direct them into a container you would be able to see if compression was coming out though them.

Look on top of a filter base and see if there’s a leak off line that goes back to the tank. It MIGHT go to the intake heater and injectors leak off line too. The banjo bolt has a small orifice that MIGHT be plugged and needs cleaning. When it’s plugged any trapped air can’t get out of the filter and it will get into the pump and cause shut down. I’ve seen it before on MF tractors.
