What fuel pump replacement to use for AW11 with 4AGZE?????

Well the in tank fuel pump on my AW11 is starting to seize due to the car sitting for about 5 years and only being started once a month. My question is what pump do i use as a replacement as i have the 4AGZE?? and how exactly do i do it??

Also do i need to run a larger pump or a surge tank with the car running about 12-14PSI of boost and possibly bigger cams??
