What TSU?

[Pstyckiewicz]

Update, bought the KDS yellow label. My wait light/glow plugs were acting weird. The wait light would come on for 1 second then go out. This would happen even cold. I could tell the glow plugs were not heating up. Put the new TSU in and back to normal with the wait light and glow plugs coming on.

Yes remove both check valves, replace with a new pieces of good quality fuel hose, IIRC 5/16 for the return line and 3/8" for the fuel supply line.
