A fuel pump pigtail would be the electrical connector and the last few inches of the wire harness before it is plugged into the fuel pump. It connects the vehicles wire harness to the fuel pump. The fuel pump pigtail is known to melt down from heat because of high resistance due to dirty/loose wire connections.
How do you wire a Pigtail for a Fuel Pump on a 97 Chevy Blazer Thank You EVa
Most fuel pump manufacturers will supply a new pigtail with a new fuel pump. This is because the pigtails have been prone to failure in the past. If you are supplied with a pigtail it would not be a bad idea to replace it. It does not usually NEED replaced though. When replacing the pigtail be sure to solder your wires carefully, and use heat shrink tubing(not electrical tape). Do not use crimp on "butt" connectors unless you want to drop your fuel tank every couple years to replace them.
We had continued problems with our fuel pump on our 97 tahoe. Finally a mechanic told us that the wiring had been recalled and it required purchasing a pigtail from the dealer. We bought/installed the new pigtail and haven't had a problem since (a couple of years now)
you will need to remove fuel tank. disconnect all fuel lines, discpnnect filler tube, disconnect electrical pigtail. note you probably have to lower but not remove fuel tank to access and disconnect above. may need to lower exhaust. remove lock ring from fuel sending unit. sending unit contains fuel pump. follow directions in fuel pump box.
On these vehicles, the wire harness to the fuel pump/ sending unit goes bad. Replace with a new updated pigtail wiring harness. The fuel tank must be removed from the vehicle to accomplish this.
1) locate the two tabs below the rear seat, actuate them and lower rear seat out 2) test both fuel pumps and identify which is in need of changing 3) disconnect the fuel line couplers, disconnect pigtail 4) rotate retaining ring 5) lift out fuel pump 6) install is reverse of disassembly
The fuel pump switch is what tells the fuel pump what pressure to pump fuel into the fuel rail
If there is fuel in the tank and it is making it's way to the fuel pump, and the fuel pump will not pump fuel, the pump is obviously defective. Replace the fuel pump with a new one.
The fuel pump is inside the fuel tank.The fuel pump is inside the fuel tank.

No, when you purchase a fuel pump you get only the fuel pump. The wiring that connects to the fuel pump is located on the vehicle and should not be removed when you remove the old pump.
