1987 Ford Ranger Fuel Pump Location: Complete Guide to Finding and Replacing Your Truck's Fuel Pump

If you own a 1987 Ford Ranger, the fuel pump is located inside the fuel tank. This is a single in-tank electric pump design for most models, though some configurations may have a second pump mounted on the frame rail. The pump sits inside a housing that also contains the fuel level sending unit and a strainer that filters debris before fuel enters the pump . Understanding the exact location and setup of your fuel pump is critical for diagnosing problems and performing a successful replacement.

Understanding the 1987 Ford Ranger Fuel Pump System

The 1987 Ford Ranger uses an electric fuel pump that engages when you turn the ignition key to the "start" position . The pump runs for about five seconds to prime the system before the engine starts. This design is different from modern vehicles, where the pump is always in the tank, but the 1987 model placed the pump inside the tank for quieter operation and better cooling.

Key fact: The 1987 Ford Ranger comes with either a single pump system or a dual pump setup depending on the specific configuration. Some owners have reported having two fuel pumps – one inside the tank and another mounted on the frame rail below the driver's side floorboard . This is more common on trucks with a rear tank or extended cab configurations.

Where Exactly Is the Fuel Pump Located?

The primary fuel pump is inside the fuel tank. To access it, you need to either drop the fuel tank or remove the truck bed. The tank sits beneath the vehicle's bed, and the pump is mounted inside the tank assembly .

For trucks with a dual pump system: The second pump (sometimes called an inline or frame-mounted pump) is located on the driver's side frame rail, typically near the fuel tank. This external pump helps boost pressure from the in-tank pump to the engine.

Fuel filter location: The fuel filter is usually located under the driver's door along the frame rail . Tracing the fuel line from the tank to the engine compartment helps you find the filter.

Step-by-Step Guide to Locating Your Fuel Pump

  1. Identify your truck's configuration. Check if you have a regular cab or super cab, and whether your fuel tank is a rear tank or center tank. This determines whether you have one or two pumps .

  2. Locate the fuel tank. The tank sits beneath the truck bed, usually centered between the frame rails. For most 1987 Rangers, the tank is under the driver's side of the bed.

  3. Find the fuel pump access. On the 1987 Ford Ranger, the fuel pump is inside the tank. There is no external access panel on the bed floor for this model year. You must drop the tank to reach the pump .

  4. Check for a second pump. If your truck has a rear tank or extended cab, look for a second pump mounted on the driver's side frame rail near the tank. This is a small cylindrical unit with fuel lines running to and from it .

  5. Inspect the fuel lines. A single pump system will have one line running from the tank to the engine. A dual pump setup may include a return line for excess fuel .

How to Diagnose a Failing Fuel Pump

Before you replace the pump, confirm that it's actually failing. Here are the most common signs of a bad fuel pump on a 1987 Ford Ranger:

Symptoms of a failing fuel pump:

  • Hard starting or no start condition
  • Engine sputtering or stalling, especially under load
  • Whining noise coming from the fuel tank area
  • Loss of power when accelerating
  • Poor fuel economy

Testing the fuel pump:

  1. Listen for the pump. Have a helper turn the ignition key to "start" while you listen at the fuel filler neck. You should hear the pump run for about five seconds .
  2. Check fuel pressure. The 1987 Ford Ranger should have fuel pressure around 40 psi . Use a fuel pressure gauge to test.
  3. Test at the fuel filter. Disconnect the inlet line at the fuel filter and have a helper turn the key. Fuel should spray out with good pressure .

How to Replace the Fuel Pump on a 1987 Ford Ranger

Replacing the fuel pump requires dropping the fuel tank. This is a moderate to difficult job that takes 2-4 hours depending on your experience . Here are the basic steps:

Tools and supplies you will need:

  • Jack and jack stands
  • Drain pan
  • Wrenches and screwdrivers
  • Fuel line disconnect tool
  • New fuel pump assembly
  • New fuel filter
  • New gaskets and seals

Step 1: Prepare the vehicle. Relieve fuel system pressure by removing the fuel pump fuse or relay and cranking the engine. Disconnect the negative battery terminal to prevent sparks .

Step 2: Drain the fuel tank. Use a drain pan to catch as much fuel as possible. This reduces weight and spill risk.

Step 3: Support and lower the tank. Use a jack to support the tank, then remove the retaining straps or bolts. Lower the tank carefully to access the pump assembly .

Step 4: Remove the pump assembly. Disconnect the electrical connector and fuel lines. Unscrew the locking ring or remove the bolts holding the pump assembly in place. Pull the pump out of the tank.

Step 5: Install the new pump. Insert the new pump assembly into the tank, making sure the strainer is properly positioned. Reconnect the fuel lines and electrical connector. Secure the locking ring.

Step 6: Reinstall the tank. Raise the tank back into position and secure it with the retaining straps. Reconnect the battery and check for leaks.

Common Problems with the 1987 Ford Ranger Fuel System

The 1987 Ford Ranger fuel system has several common issues due to age and ethanol-blended fuels . Ethanol's corrosive properties accelerate rubber and plastic degradation within the pump.

Typical fuel pump problems:

  • Pump failure due to age and wear
  • Clogged fuel filter
  • Faulty fuel pump relay
  • Damaged wiring or connectors
  • Rusty fuel tank causing debris in the fuel system

Preventive maintenance: Replace the fuel filter every 30,000 miles. Use fuel stabilizer if the truck sits for long periods. Keep the fuel tank at least half full to prevent the pump from running dry and overheating.
