The arrow is the direction of flow, so by following the arrow, it will take you up towards the engine. Does this answer the question?

Well just go in the opposite direction of the arrow and you tell me! I think it's tank, pump, filter, engine, not 100% sure though.

Yeah I think I'm right because those are high pressure fittings on the filter, so it's going into the filter at high pressure, meaning already through the pump.
