1993 Nissan Pickup Fuel Pump Location: Where to Find It and How to Replace It

If you own a 1993 Nissan Pickup (also known as the D21 Hardbody) and are dealing with starting issues, stalling, or loss of power, the fuel pump is a likely suspect. The fuel pump on a 1993 Nissan Pickup is located inside the fuel tank. This is an in-tank electric pump, meaning you have to drop the fuel tank to access and replace it . This is not a simple job, and it requires careful preparation and the right tools. This guide will walk you through the exact location, symptoms of a failing pump, the replacement process, and how to choose the right part for your truck.

Where Exactly Is the Fuel Pump Located?

The 1993 Nissan Pickup uses an in-tank electric fuel pump. This means the pump is mounted inside the fuel tank itself, not on the engine or along the frame rail like on older vehicles. Both the 2.4L 4-cylinder and the 3.0L V6 engines use this same in-tank design . The pump is part of a larger assembly called the fuel pump module, which includes the fuel level sending unit (the part that tells your gauge how much gas you have) and a strainer. To get to it, you must remove the fuel tank from the truck .

Common Symptoms of a Failing Fuel Pump on a 1993 Nissan Pickup

Before you drop the tank, you should confirm the fuel pump is the issue. Look for these common signs:

  • No Start Condition: The engine cranks but will not start. This is one of the most frequent complaints on older vehicles .
  • Loss of Power at High Speeds: The truck may run fine at low speeds but struggle or hesitate when you try to accelerate or go uphill .
  • Engine Stalling: The engine may stall, especially when the tank is low on fuel. This is a classic sign of a failing pump that is overheating.
  • Whining Noise from the Fuel Tank: A healthy fuel pump makes a quiet humming sound when you turn the key to the "ON" position. If you hear a loud whining or screeching noise from the rear of the truck, the pump is likely failing .
  • Rough Idle: A failing pump can cause inconsistent fuel pressure, leading to a rough idle or poor performance .

Step-by-Step Guide to Replacing the Fuel Pump on a 1993 Nissan Pickup

Replacing the fuel pump is a moderately difficult DIY job that requires dropping the fuel tank. The process is similar for both the 2.4L and 3.0L engines . Here is a general overview of the process.

Safety First
Working with gasoline is dangerous. Always work in a well-ventilated area, keep a fire extinguisher nearby, and wear safety glasses and gloves. Never smoke or work near open flames.

Step 1: Relieve Fuel System Pressure
Before you do anything else, you must depressurize the fuel system. Locate the fuel pump fuse in the fuse panel under the dashboard. Remove the fuse, then start the engine and let it run until it stalls. This uses up the pressurized fuel in the lines. After it stalls, crank the engine for two to three more seconds to clear any remaining pressure .

Step 2: Disconnect the Battery
Open the hood and use a 10mm socket to loosen the negative battery terminal clamp. Remove the cable and move it away from the battery post to prevent any electrical sparks during the repair .

Step 3: Drain the Fuel Tank
A full fuel tank is very heavy and dangerous to drop. Use a siphon pump to remove as much fuel as possible into an approved gas can. This will make the tank much lighter and safer to handle .

Step 4: Raise the Vehicle and Support It
Jack up the rear of the truck and support it securely on jack stands. Never work under a vehicle supported only by a jack. You will need to work under the truck to access the fuel tank straps and lines.

Step 5: Disconnect the Fuel Lines and Electrical Connector
The fuel lines and the electrical connector are located on top of the fuel tank. Use a fuel line disconnect tool (5/16-inch or 3/8-inch) to release the quick-connect fittings . Pull the fuel lines straight off and immediately plug or wrap the line ends with a clean shop towel to prevent dirt from entering. Unplug the electrical connector from the top of the pump module.

Step 6: Remove the Fuel Tank Straps
The fuel tank is held in place by two metal straps. Use a socket and wrench to remove the bolts that hold the straps. Carefully lower the tank a few inches to ensure all lines are disconnected, then remove the straps and lower the tank to the ground.

Step 7: Remove the Old Fuel Pump Assembly
The pump assembly is held in the top of the tank by a large lock ring. Use a brass drift punch and a dead-blow hammer to tap the lock ring counterclockwise until it loosens, then lift it off. Do not use steel tools or power tools near the open fuel tank . Lift the old pump module upward slowly, tilting it slightly to clear the fuel level float arm. Place the old pump into a drain pan.

Step 8: Install the New Fuel Pump Assembly
Place the new seal gasket into the groove on the tank opening. Lower the new pump module into the tank, guiding the float arm carefully. Install the lock ring and tap it clockwise until it is tight. Reinstall the fuel tank, reconnect the fuel lines and electrical connector, and tighten the straps.

Critical Step: Replace the Fuel Filter
Always replace the fuel filter when you replace the fuel pump. A clogged filter is often what caused the original pump to fail in the first place .

Reconnect the Battery and Test
Reconnect the negative battery cable. Turn the key to the "ON" position and listen for the pump to prime (a whirring sound). This lets you check for leaks before starting the engine. Once you confirm there are no leaks, start the engine and let it run.

Which Fuel Pump Part Number Do You Need for a 1993 Nissan Pickup?

Choosing the correct part is essential. The 1993 Nissan Pickup (D21) came with two main engine options, and the fuel pump assembly can differ.

  • For the 2.4L 4-Cylinder (KA24E) Engine: The OEM part number is 17040-59G00. This pump was used on 1992-1993 models and has been superseded by part number 17040-8B000 . Many aftermarket pumps are designed to replace this number.
  • For the 3.0L V6 (VG30E) Engine: The OEM part number is 17042-11G01 .

Always verify your engine type before purchasing a new pump. It is also a good idea to check the Nissan Parts Deal website or a local parts store to confirm fitment for your specific VIN and trim level .
