2004 to 2008 15 25 and 3500s you'll need new fuel injectors from 1aauto.com Flat blade screwdriver 8 to 10 mm sockets with a ratchet and extensions angled pick Rag and some fuel system safe cleaner behind the inner wheel well liner on the driver's Fender you'll find a large Connector running to the rear harness of the truck using the flat blade screwdriver pry back the red safety as far as you can lift up on this gray latch here you may have to push down lift up on the gray latch open that up all the way you don't have to remove this connector you just have to open the latch to separate the terminals open the fuel door and remove the fuel cap now when we start our truck it's going to die we want to keep cranking for a few seconds after it dies to run the system out of fuel before we try to remove our fuel [Applause] rail you want to use a 10 mm wrench to remove the negative terminal of your battery and set it off to the side open the airbox by releasing the metal Clips on the side and the rear pop it out of its holders release this hose from the front and using a flap blade screwdriver loosen the clamp on the rear of the inlet pipe with that loosened up work the pipe off of the Box remove this assembly the bottom half of your airbox simply lifts off its retainers comes right out of the truck remove the 2 10 mm bolts one behind the alternator one behind the oil cap with a 10 mm socket ratchet and extension lift up on the airbox so you can access the intake air temp sensor at the front push down on the connector remove it from the i8 at remove the airbox from the vehicle on the passenger side of the fuel rail remove the cap on the shraer or pressure release valve using a thick rag or paper towel place that below the valve to catch any excess fuel that comes out using a small pick press down on the tab in the center of the valve now that we know that all the fuel pressure has been released from our system we can begin to remove the rail and our injectors using an 8 mm socket and Ratchet remove these two screws these are the same on the driver's side if the injector you're replacing is over there before removing your injectors you'll notice we have a lot of dirt and debris up on the top of our manifold once the injectors are out we risk having that fall into the motor if you have access to compressed air it's nice to be able to blow this out otherwise you can use some cleaner and a paper towel or rag to remove anything that may fall into the injector holes using a small flat blade screwdriver pry up on the red safety tab for the injector you intend to remove push down and remove the connector from the injector lift up on the fuel rail you want to try to do this evenly and pop out one side of the rail at a time you may have to work it a little bit side to side to get the injectors to come out on the back side of the injector use a small flat blade screwdriver to pop out the retaining clip for the injector try to keep a hand on these or at least a good eye on them because when they come off they do tend to go flying it's not something you want to lose with the fuel rail pulled up and the clip off of your injector pull down and work the injector out of the fuel rail it may leak a little bit of fuel once youve remove the injector but that's all right here we have our old injector from the vehicle and our new injector from 1A Auto as you can see they're the exact same injector same size same sprayer nozzle same o-ring seal both to the fuel rail and into the intake manifold as well as the same electrical connector reinstall the fuel injector into the fuel rail you may want to use a little bit of clean fuel from the rail to lubricate the gasket reinstall the metal clip from the back side check for debris at the other injectors press the rail back into the manifold you can use some clean fuel as a lubricant to help reinstall the lower gasket on the injectors reconnect your injector push down on the red tab reinstall your two 8 mm bolts screw the cap back onto your shider valve this process for the the injectors while we did the front passenger side is going to be the same for any injector on either side of the rail on these motors reinstall the end of the airbox with the silicone gasket over the end of your throttle body tighten up the bolt behind the oil fill cap and behind the alternator with a 10 mm socket and Ratchet and an extension reconnect the intake air temp sensor drop the lower air filter housing back onto its mounting locations be sure the air filter is fully seated into the housing reinstall the intake tube onto the airbox and the PCV breather hose lock the lid of the airbox back onto its hinge close it lock it back down and tighten the intake tube clamp with a flat blade screwdriver bring the latch on the connector back down reinstall the red safety tab reinstall your fuel cap reinstall your negative battery terminal tighten it back with a 10 mm socket now since we released all the pressure and fuel from the fuel system and the fuel rail we'll have to Prime our fuel system we do this by inserting the key turning the key to the on position for 3 seconds turning it off and repeating that process three times before starting now may be a little hard to start at first because of the fuel and the cleaning agents that made it into the motor it may rev high or run rich but it'll all smooth out in a few seconds there's our high idle and after a few seconds of running the idle evens out and drops down to normal levels thanks for tuning in we hope this video
