get rid of the fuel pre heater. get a spin on filter housing or a filter with out the preheater. replace your in and out lines with transparent polyurethane. get rid of your water seperator.
hasn't had a preheater on it since I got it, if not ever.

Also can extend the life or improve operation of a dying Inj Pump.
How does that Tee preheat? there is no externall power going to it?
I just dont understand where the fuel is going if I have the lines both blocked?
