Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video we're going to show you how to relieve the fuel system pressure in this Dodge Ram, this one's a 2008. We're also going to show you how to prime the fuel system once the pressure's been released. You'll need a flat blade screwdriver, 10mm socket with a ratchet and extension, an angled pick, and a rag.
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.
Open the air box 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 the flat blade screwdriver loosen the clamp on the rear of the inlet pipe. With that loosened up, work the pipe off of the box, and remove this assembly. Remove the two 10mm bolts, one behind the alternator and one behind the oil cap, with a 10mm socket, ratchet, and extension. Lift up on the air box so you can access the intake air temp sensor at the front, push down on the connector, remove it from the IAT, and remove the air box from the vehicle.
On the passenger's side of the fuel rail, remove the cap on the Schrader, or pressure release, valve. Using the thick rag or paper towel, place that below the valve to catch any excess fuel that comes out. Using the small pick, press down on the tab in the center of the valve. After depressing the Schrader valve several times, no more fluid coming out means there's no pressure left in your fuel system.
Screw the cap back onto your Schrader valve. Reinstall the end of the air box with the silicon gasket over the end of your throttle body. Tighten up the bolt behind the oil fill cap and behind the alternator with a 10mm socket and ratchet and an extension. Reconnect the intake air temp sensor. Reinstall the intake tube onto the air box and the PCV breather hose. Lock the lid of the air box 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. 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 three seconds, turning it off and repeating that process three times before starting.
