Changing your electric fuel pump can be done in less than an hour at home, usually with basic tools. This article covers fuel pumps that are located outside the fuel tank. The pump can often be found on the driver's side chassis frame rail, underneath the vehicle, connected with the fuel filter. Check with a model specific group online if you are unable to locate it. Pumps located within the fuel tank often require complete fuel tank removal and are beyond the scope of this article.

Difficulty: Moderate

Instructions

Things You'll Need:

Needle-nose pliers
Flat-blade screwdriver
Rags and liquid absorbent (such as cat litter)

Fuel Pump Changeover

Step 1

Remove the electrical fuse for the fuel pump. Crank the engine for about 20 seconds to relieve pressure in the fuel lines.
Step 2

Detach the electric connector from the fuel pump. Use the flat- blade screwdriver to pry the retaining clip upwards as you separate the connector halves.
Step 3

Using the needle-nose pliers, remove the fuel line attachment clips. These are often a two-pronged plastic clip. Be sure to have rags on hand to catch spilled fuel.
Step 4

Remove any hardware or straps that may be holding the pump in place.
Step 5

Mount your new fuel pump, taking care that the flow arrow is pointing forward in the direction of the engine.
Step 6

Reattach the fuel lines, using new attachment clips. Reconnect the electric connector. Be sure the retaining clips lock in place.
Step 7

Replace the electrical fuse, start the vehicle and check for leaks.

Tips & Warnings

If you have bell shaped connectors on your fuel lines, you may need a fuel line disconnect tool to separate the internal locks. You can often find a set that fits most any vehicle for less than $25. Fords and other vehicles may have a fuel pump safety shutoff that has disabled your vehicle after a sudden stop or harsh bump. Consult your owner's manual; a reset button may be located under the dash.
Never smoke or utilize open flames while working with fuel lines and pumps.
