Fuel Stabilizers, to use or not to use?

[CornHusker4Life]

Quick Background,

I have a 98 Silverado 1500 4x4 5.7 with 14k miles. It has only had 90+ octane in it since new. I just had to replace the factory fuel pump and fuel filter due to large amounts of residue/gunk in the tank(tank was cleaned also). I only drive it about once a week on nice days. Should I use a fuel stabilizer in the tank or how should I store it between drives. I always fill the tank completely before it goes back in the garage.

Thanks, Jarrod
