ELECTRIC PUMP

REMOVAL

1. Before servicing the fuel pump the fuel system pressure must be relieved. See: Fuel Pressure Release
2. Disconnect the negative battery cable.
3. Raise the car on a hoist.
4. Remove the fuel tank. See Fuel Tank / Service and Repair.
5. Remove the fuel tank sending unit and pump assembly by turning the cam lock ring counterclockwise. Lift assembly from the fuel tank.
6. Pull the fuel pump up into the attaching hose while pulling outward away from the bottom support. Take care to prevent damage to the rubber insulator and strainer during removal. After the pump assembly is clear of the bottom support, pull the pump assembly out of the rubber connector for removal. NOTE: Inspect the fuel pump attaching hose for any signs of deterioration. Also check the rubber sound insulator at the bottom of the pump. Replace damaged or deteriorated parts.

1. Push the fuel pump assembly into the attaching hose.
2. Position the fuel tank sending unit and pump assembly into the fuel tank. Use a new "O" ring seal. NOTE: Care should be taken not to fold over or twist the strainer when installing the sending unit as this will restrict the flow of fuel. Also, verify that the strainer does not block the full travel of the float arm.
3. Install cam lock over the assembly and lock by turning clockwise.
4. Reinstall fuel tank.

1. Disconnect fuel lines from fuel pump.
2. Remove fuel pump mounting bolts and the fuel pump.
3. Remove all gasket material from the pump and block gasket surfaces. Apply sealer to both sides of new gasket.
4. Position gasket on pump flange and hold pump in position against its mounting surface. Make sure rocker arm is riding on camshaft eccentric.
5. Press pump tight against its mounting. Install retaining screws and tighten them alternately.
6. Connect fuel lines. Then operate engine and check for leaks.

SOURCE: fuel pump wiring diagram for 2001 chevy S10

If the ONLY thing you want to put a toggle switch in, is to add a security device, then no, there would be no draw backs, except for the thief, that might want to steal your truck, other than that, yes there could be...the computer controls the grounds, and a few of the hot wires, in order to control certain parameters...and yes, it controls your fuel pump as well...do not interrupt the signal, because if you do, you may end up with other codes pertaining to the mistake of "jury rigging" your vehicles wiring.
Make sure that you wire the Pump "inline", don't add an alternate electrical supply source, where the positive wire is, cut that wire, attach one cut side to one section of the toggle switch, the other cut section to the other connecter for the toggle switch...Good Luck

SOURCE: i mixed up the wires on top of the fuel pump on a 1996 chevy s10 where do they go?

Looks like you have a gray wire for the pump, a black for ground, pink for the sending unit, and a gray-dark green for the pressure sensor.
