Remove the fuel pump if all else fails. Two bolts hold it on.

Try taking a hammer to the screwdriver and pierce the filter. If that doesn't break it free, remove the fuel pump for more clamp options.

To reinstall the fuel pump, replace the gasket, and you might have to buy a remote starter button to turn over the engine (disconnect the coil wire first so it doesn't start on you) you want to bump the engine just enough so that the internal cam that actuates the fuel pump arm is at its flattest point. Otherwise you will have a heck of s time reinstalling the pump while compressing the internal pump arm. Bumping the engine to the cam flat spot makes the installation simple.
