The mechanical fuel pump provides fuel to the carburetor and is
actuated by an eccentric on the camshaft through the rocker arm or
push rod. An inlet line from the fuel tank is connected to the fuel
pump with a flexible hose and hose clamp. The outlet line to the
carburetor is made of steel and connected to the fuel pump
with a tube fitting.
When you replace a fuel pump, also install a new fuel filter. Check the flexible fuel line running
from the fuel tank to the fuel pump, and replace it if it's cracked or leaking. If you replace the
fuel line, you should also install a new hose.
These instructions will help you replace your Land Criuiser mechanical fuel pump.
Note: The system operates under pressure and require special service precautions. READ the service
manual completely before you begin.
Tools & Equipment You'll Need
Ratchet wrench set with universal joint
Tubing or open-end wrenches

Before You Begin
Get the correct fuel pump for your Land Cruiser. If needed, also get fuel
line hose and clamps, a fuel pump gasket, and gasket sealer
or cement. Gather together all the necessary tools.
Work in a well-ventilated area away from sparks or open
flames. DO NOT SMOKE. Let the engine cool.
Disconnect the battery ground cable.
Old Pump Removal
1. Disconnect the fuel tank hose at the fuel pump, and plug the
hose with a bolt or wooden dowel to keep any fuel from flowing
2. Disconnect the outlet line to the carburetor. Use a wrench on
the fuel pump fitting and another on the line nut.
3. Disconnect the two attaching bolts and remove the old fuel
pump. Clean off any old gasket material from the mounting
surface of the engine.
New Pump Installation
1. Coat a new fuel pump gasket on both sides with gasket sealer
or gasket cement. Put the attaching bolts through the new
pump and slip the gasket over the bolts.
2. Install the new pump on the engine. Make sure that the rocker
arm in the pump is against the eccentric inside the engine, or
that the push rod is correctly installed in both the engine and
the fuel pump.
3. Attach the fuel outlet line that runs to the carburetor. If it's
difficult to connect, remove the other end of the line from the
carburetor. Connect the line to the fuel pump, and then
reattach the other end to the carburetor. Use a wrench to hold
the fuel pump fitting and tighten the line nut with another
4. Attach the fuel inlet hose from the gas tank, and the vapor
return hose (if the Cruiser is equipped with one). Tighten all
5. Reconnect the battery ground cable, start the vehicle and
check for leaks
