say it depends where it is, and how much yhour replacing, if its just the pipe where it does the 180degree turn back into the flexi you could just join it in next to the tank before it goes over it, it runs next to the fuel lines, its a male join into the flexi pipe, and youll obviosly need a male and a female union if youre piecing it in, dont think the pipe has another join in it until it goes into the abs unit, id try not let the resevior run dry if possible, the abs can potentially be a nightmare to bleed if it gets air in it
