How to Replace an Isuzu Fuel Filterby Alibaster Smith
The fuel filter in an Isuzu cleans the fuel before it gets to the fuel injectors. This is necessary in order to remove most of the contaminates in the fuel. Contaminates are naturally found in the underground wells at a gas station, and even in the gas tank (as rust). Obviously, contaminates are no good to an internal combustion engine. Replace your fuel filter every 30,000 miles so the filter can do its job.
Remove the fuse for the fuel filter. The fuse is inside the vehicle in the fuse box underneath the dash. Refer to the diagram on the underside of the fuse cover if you cannot find the designated fuse. Use the supplied fuse puller to remove the fuse.
Start the engine and allow it to stall out. This will relieve pressure in the fuel system.
Locate the fuel filter. On Isuzus, the filter is under the rear passenger-side frame rail. The fuel filter is easily accessible from the side without having to jack up the vehicle.
Place a catch pan underneath the fuel filter.
Remove the 10 mm screw bolt that holds the filter in place.
Remove the spring clips with a pair of pliers. Pinch the tabs of the clips together and slide the clip off the end of the hose.
Remove the hoses running to the filter. Each end of the filter has a hose that connects to the filter. Pull these hoses away from the filter and allow the gas to drain off into the catch pan.
Pull the filter down to remove it, and install a new filter. Installation is the reverse of removal.
