Fuel Filter Question (easy)

When you replace a fuel filter, what do you use to plug the fuel lines? I can't seem to find anything that works.
note: this is for a fuel injected system

i dont plug it, you dont lose that much fuel anyway.

Wait overnight without running the car and the pressure will bleed back through the pump. If you try to do it within a few hours of running the car, the fuel will still be pressurized.

What I did, was to disconnect the plug to the fuel pump, then tried to crank the car for 2 or 3 seconds. That cleared the lines as well.

My car is a diesel, this might not work for you, but when I change my fuel filter I plug the fuel lines with golf tees.
