If your vehicle still has difficulty getting fuel and your tank has fuel, you may need to clean or replace the fuel pump. The Mercury Cougar’s variety of styles and trim levels can affect your choice of fuel pump.
How can I replace the fuel pump seal?
Remove the fuel pump’s electrical connector and the fuel lines. Remove the locking ring from the fuel pump with fuel tank sender wrench D84P-9275-A and take out the fuel pump. Discard the old O-ring seal. Install the new fuel pump using the items included in the kit and be sure to replace the O-ring seal.
What can I do if my fuel pump is not producing enough pressure?
If you suspect that your fuel pump is not producing enough pressure, there are two tests you can perform. The first is a simple pressure output test. Many inexpensive old-school vacuum testers can read mechanical fuel pump pressure just as well as vacuum pressure .
What kind of test can I do on my fuel pump?
The first is a simple pressure output test. Many inexpensive old-school vacuum testers can read mechanical fuel pump pressure just as well as vacuum pressure . To perform this test, you should connect the test gauge to the metal output line using a spare piece of rubber fuel hose and a clamp.

What are the symptoms of a fuel pump relay problem?
1. Engine stalls One of the first symptoms of an issue with the fuel pump relay is an engine that suddenly stalls. If the fuel pump relay has an issue while the vehicle is operating it will cut off power to the fuel pump, which will cause the engine to stall.
Where is the fuel pump control module located?
It is often found in the fuse box located in the engine bay and functions as the primary electronic switch that controls power to the fuel pump. The fuel pump relay is usually controlled by the ignition or Powertrain Control Module , and when switched on, will provide current to the fuel pump so that it may function.
What kind of engine does a Mercury Cougar have?
Models made from 1967 to 1970 were equipped with 289 cubic inch (ci), 302 ci, 351 ci, 390 ci, 427 ci and 428 ci engines. Models built from 1970 to 1973 used 351 ci and 429 ci engines.

Where are the numbers on the fuel pump relay?
Connect your fuel pressure gauge to the Schrader Valve on the fuel rail. Disconnect the fuel pump relay from its connector. Locate the terminals labeled with the numbers 3 and 4. Using a jumper wire, jumper terminals 3 and 4 together.
How can I Stop my Mercury Villager from leaking fuel?
Raise and support the Mercury Villager. Remove the fuel hose clamps, and then disconnect and plug the hoses to prevent them from leaking fuel. Take the fuel filter out of the bracket. Install the new filter in the bracket with the arrow pointing toward the engine, in direction that fuel flows through the system.
How does the fuel filter work on a Mercury?
The Mercury car fuel filter attaches to the fuel line and strains the fuel for any impurities. The fuel is then sent to the fuel injector before it flows into the engine.
How do you remove fuel filter from fuel line?
Disengage the fuel filter from the fuel line by depressing the spring lock couplings on the release tabs. The filter should simply fall away from the fuel line when the couplings are pushed together with enough pressure. Remove the filter.

How do you replace a fuel filter on a tracer?
Raise the Tracer’s front end with a floor jack and support it on jack stands. Disconnect the hose at the bottom of the fuel filter, removing its hairpin clip like the earlier one. Lift and remove the filter from the car. Install the replacement fuel filter within its bracket and clamp, tightening the clamp.
How do you remove a fuel tank from a Mercury?
Pull the fuel tank out from under the Mercury and set it carefully on the ground. Wrap a rag around the tip of a flathead screwdriver; place the tip of the screwdriver against the retaining ring holding the fuel pump in place and carefully tap the screwdriver with a mallet to turn the ring until the fuel pump is free.
When to replace the fuel pump on a Mercury?
If you own your Mercury long enough, you are bound to be faced with replacing the fuel pump sooner or later. Drive the Mercury until you are just about out of gas. Park it where you will perform the work and pull the fuel pump relay (located in the relay box under the hood) while the engine is running.
How to change the fuel pump on a Mercury Mountaineer?
Lift the fuel tank back into position and bolt the retaining straps back in place. Plug the fuel pump relay back in, reconnect the negative battery cable and turn the key to the run position and listen for the pump to cycle. Do this four more times before starting the Mercury.
How to rebuild a Mercury outboard fuel pump?
This video shows you how to rebuild a Mercury or Mariner outboard fuel pump. The one shown is from a 1997, 90 HP Mercury carbureted model. I will remove it, disassemble it, and re-assemble it. The rebuild instructions are at the end of the video. Loading…
Where is the test point for a fuel pump?
Hook the pressure gauge to the fuel pump test fitting. Locate your fuel pump test point, which is usually near the fuel injectors, and locate the point at which the pump hooks up with the filter injector rail. There should be a separation joint or a test port, where the pressure gauge attaches.
Where can I get a fuel pump gauge?
Get a fuel pressure gauge. Commonly available at most auto parts stores for $20-30, a pressure gauge is a good investment, useful on most makes and models of cars. If you don’t want to buy one, you can also often borrow one from machine shops or auto shops who have them to lend.
Why is my fuel pump relay not working?
This code is the result of the pcm not detecting power in the Fuel Pump circuit after commanding the fuel pump relay on. Most common culprit with this code is a failed relay, although an open in the feedback circuit to the pcm can be the cause as well (especially if the Fuel Pump is running at the time the code is set).
