You will also most likely need a new ONE HOLE fuel accumulator ( sold separately ) especially if the car has not been regularly driven or has been sitting in storage for long periods.  Also, be sure to check out the condition of your tee hose for the accumulator. This also would need to be purchased separately if you need to replace it. See related products below:
