Ford F150 Codes P0171 & P0174

Q. Hi, I have a 1998 Ford F150 with a 4.6 liter V-8 with 73,000 miles, and an automatic transmission. My check engine light is staying on all the time. It has been on for about 2,000 miles now. I went by Auto-Zone to have the code read and it came up to be P0171 and P0174. Can you help me please?
