Ever pushed your car with a fresh tune and wondering why it’s keeps leaning out on hard throttle transitions? It could be that you’re running an aging fuel pump and it’s simply not keeping up with your car’s new fuel requirements. When you really think about it though, the factory fuel pump is probably nearly at it’s end of life considering it’s over 10 years old!
It’s had a good life and run for it’s money, time to retire it and replace it with something more efficient and new!

Open the fuel cap to relieve pressure from the fuel tank.
Remove the rear trim covering the battery, fuse & relay section.
Remove anything obstructing the fuel tank access, in this case my audio equipment.
Remove 4x 10mm access bolts to the fuel tank’s lid and disconnect the fuel pump and fuel level sensor gauge connectors.
Using your hands, undo the locking ring of the fuel tank and fuel pump cradle lid. This is where it can be tricky and may cause injury to knuckles. The locking ring can be undone by turning it anti-clockwise.
Disconnect the fuel level sensor connector and slide out the entire fuel pump assembly. It will be attached to the wall of the fuel tank in a slot. You can easily feel for it on the slope side of the fuel tank.
Remove old fuel pump by disconnecting the wires and hose clamps. You will notice the fuel pump isn’t really attached to anything and sits in place by the placement and the hose at the top.
Step 8 (Optional):
Replace the existing hoses with E85 compatible fuel hose, make sure they are the same length as the factory hoses or else you won’t be able to fit the fuel pump assembly back into the fuel tank.
Fit new fuel pump in place, you will notice that the fuel pump will not be seated properly on the cradle. Using a hose clamp, centre the fuel pump and secure using the hose clamp. At the same time, replace all spring type hose clamps with the worm drive ones.
Cut wires and heat shrinks and attach to the fuel pump’s connector.
Re-install fuel pump, connectors and fuel tank lid. A trick is to grease up the seal as it makes fitting it heaps easier.
Wasn’t that hard was it? Just a side note, if you’re installing a current hungry fuel pump I suggest the fuel pump be wired using a relay directly to the battery. The stock wiring and fuel pump controller cannot cope with the new current draw resulting in a drop in voltage causing lack of performance and further issues.
