Redman, sorry for stealing your thread, my Destroyer is doing the same thing, first I thought this was normal, but your thread got me thinking about the situation, either the fuel line in the tank is damaged, the flange is cracked or possibly the pressure regulator on the TB is bypassing prematurely.
Things we both need to investigate:
I had siphoned the fuel tank of questionable fuel last weekend and fear I might have damaged the line in the tank.
I'm gonna run a pressure test and pull the tank head off to check out the innards.
One of my maintenance plans was to make sure these lines had not weakened after sitting so many years without use.
Noted in my New Destroyer thread, my issue is not the same as yours (they are wired & controlled differently), you need to check the fuel pressure suggestion, the system relays and possibly the ECM for the continuous pump run condition.
