b Before assuming that the fuel pump is a gonner, make sure that you are getting 12vdc (or more but not less) at the pump. I'm not sure about your '78 wiring, but my '73 GTV has a dedicated fuel pump fuse located in its own housing by the fuse box. b Check the voltage and the fuse.
Fuel pump selection is determined if you have the original SPICA FI or if the SPICA has been replaced with carbs. SPICA FI requires the high pressure/high volume pump (http://goo.gl/LYCgIF) whereas carbs require the other (http://goo.gl/8j6TyN). Changing out the fuel pump isn't hard but can be messy due to the fuel line from the gas tank. If you can't drain the tank, then purchase some fuel line pliers (http://goo.gl/VG193H) to clamp on the fuel line from the tank to the pump. If you have the original fuel pump, the OD is different than the newer models so you might have to fiddle with the clamp holding the pump to the car. While down there, you should replace all the flexible fuel lines with new ones. I can't remember the sizes needed. When was the last time you replaced the tank fuel filter? Good idea to replace it while you are all covered with gasoline... I like NAPA Gold fuel filter 3299 (http://goo.gl/7YKdkl) which has .5" OD connectors which match up with the 12 mm outlet from the tank. Use .5" fuel line here.
