Steps replacing a 1985 grand marquis fuel pump for first time alone thanks

See Figure 1
Two different electric fuel pump configurations were used on fuel injected models. One consists of a low pressure in-tank boost pump in conjunction with an external, frame-mounted high pressure pump. The low pressure pump is used to provide pressurized fuel to the inlet of the high pressure pump and helps prevent noise and heating problems. System pressure is controlled by a pressure regulator mounted on the engine.
The other configuration consists of an in-tank high pressure pump which does not utilize a boost pump.

  4. Disconnect the fuel supply, return and vent lines at the right and left side of the frame.

How to replace a 2005 grand am 6 cyclinder fuel pump

You need to drop the fuel tank...pump is inside. remove the screws under the fill neck opening that hold it to the body, disconnect the fuel line connections and harness, remove both straps holding the tank in (support it, if there is fuel inside its very heavy).Remove the fill and vent hose from the tank. Remove the collar that holds the pump in and carefully remove the pump assembly. Carefully replace pump and make sure it goes in without damaging the float arm and points in the same direction the old one did. reverse order...put it back together. It's best to drain tank and clean the inside before putting it back up. NO SMOKING< ELECTRIC TOOLS OR OTHER IGNITION SOURCES WITHIN 75 FEET OF WHERE YOU ARE WORKING!!!
