Aft fuel shutoff?

[Toolatenow]

I have a minor diesel leak on drivers side. Found it to be the aft fuel shut off solenoid. I'm trying to get a better understanding of this and if a bypass is feasible? Under acceleration while loaded I hear fast ticking and an engine light until turbo boost drops. Replaced airline going to this device and had no change. I no longer have anything in the cans so dont see the need for this but I dont have a good understanding. [attachment=8498]
