2004 Gallardo fuel filter replacement
Fuel filters x2 PN: 400201511A
Sealing washers x2 PN: 400201349 (recommended)
We’re unable to tell you exactly what tools you need because believe it or not, it will change from car to car. Just be prepared for unexpected things as you start your own work. You never know who was there before you so bolts/screws may be missing or changed because they were misplaced when removed previously (hence the need for an “assortment”)
-First you’ll need to start by removing the side panels and rear louvered panel in the engine bay. These are normally secured by torx screws.
-With all of the screws removed from the side panels you’ll need to temporarily detach the engine hood strut. To remove the hood strut simply wedge a flat head screwdriver under the retaining clip at the end of the strut and push the clip towards the end. Do not completely remove the clip from the strut as chances are it will shoot across the garage and be lost forever L . The clip only needs to be pushed slightly out of the way to disengage the ball pin. Once the strut is disconnected unscrew the ball pin, remove the panel and then reinstall the ball pin and strut. Repeat for the opposite side.
Caution: Depending on the strength, one engine strut may be enough to hold the engine hood stationary while you work. We recommend bracing the hood at the latch with a piece of wood for safety.
-With the panels removed you will be able to easily see the LH fuel filter. The RH fuel filter is located behind the coolant reservoir.
Left Hand filter removal
-The charcoal canister will need to be removed. There are slight changes in the routing of the hoses throughout the year range on the Gallardo so adjust your approach as needed. These hoses all have press snap fittings and can be removed by hand. Place towels under the fittings before removing the hoses to catch any fuel
TIP: You may need to squeeze the release tabs and push forward before pulling away from the canister. This will alleviate any constant pressure on the retaining clip inside the hose that would prevent you from disengaging the clip with your fingers.
-Remove the bracket holding the charcoal canister in place. Depending on the year of your Gallardo you may need to do this to before trying to disconnect the hoses. Removing the bracket will give you more room to work with the clips.
-Now you have access to the left hand fuel filter. The side of the filter closest to the outside of the car has the same type of hose with a snap fitting on it (same as the charcoal canister).
-Remove the single screw holding the retaining strap on the fuel filter.
-Unscrew the fuel filter from the fuel line that feeds the fuel rail
-Transfer the fittings from the old filter to the new filter. This is where you will install a new sealing washer if necessary (400201349). The washer will seal between the filter and the fitting for the hose with the snap fitting (points towards the outside of the car).
-Install in the reverse order
Right Hand filter removal
-Unbolt the coolant reservoir. One bolt holds the reservoir stationary and on the opposing side are two rubber buffers that are pressed into a support bracket.
-With the reservoir free you should be able to rotate the reservoir forward and rest it against the intake manifold. Take caution when doing this as the coolant hoses may be extremely brittle. If the hoses are brittle I would recommend removing them completely and taking the reservoir out entirely to prevent any unneeded replacement work. Our coolant lines were very brittle, ended up splitting and needed replaced… not fun for such small hoses.
-With the reservoir out of the way you can gain access to the right hand fuel filter. This is secured the same way as the left.
-Transfer your fittings to the new filter and install a replacement sealing washer if necessary (400201349).
-Install in the reverse order.
Before installing the side panels we recommend you start the car and let it idle for a few moments. You’ll want to do this a few times to make sure enough pressure is built back up in the fuel lines. This will reveal any leaks at the filters now instead of on the road with open flame later. If you haven’t already, keep your fire extinguisher close by just in case (we always have one handy when dealing with fuel).
Congratulations, you’ve changed your fuel filters!
