For the front two you need to use line rated for Fuel Injection, I think it is 5/16" but I'm not sure, just take a section of it to the parts store, they sell it by the foot. You also need to use hose clamps made for fuel injection hose, the two clamps on the stock fuel filter next to the coolant tank are proper FI clamps.

If you want to minimize fuel spray, cut power to the fuel pump while the engine is running. The car will die off after a few seconds once the fuel pressure drops down. You will still get some fuel coming out when you disconnect the hoses so have a rag ready and wear some eye protection. If you want to be real safe have an extinguisher handy.

It would be best to completely replace the lines, but please for now at least get some clamps on there.
