For a fellow Pats Fan...anything!
You need new lines, a coupler, and tank/regulators. By the looks of those lines, cleaning won't help, just get new ones.
MicroMatic sells
kits that you can buy to get all of the parts you need. Realistically, I think you only need lines, couplers, clamps, regulators, and a tank. Your tower, faucet and shank should be ok. Tough to tell from the photo.
They (MM) has a video about setting it up,
check out beer education.
