How to Pressurize a Car's Fuel System

Video Transcript

Hi, my name is Nate McCullough, on behalf of Expert Village. In these following clips, we're going to talk about removal and replacement of the vehicle's fuel filter. In this clip we're going to talk about priming your vehicle's fuel system, and inspecting for leaks. Being that we opened it, we're going to want to cycle our ignition key on and off several times. What that will do is engage the vehicle's fuel pump, get the air out of the system, and bring it up to pressure. Like I said, cycling the key about three or four times will do an adequate job of refilling our fuel filter. They don't come filled with gasoline, unfortunately enough. We're going to have to fill that and the rest of the system, and from there, once we've got it primed we'll inspect for any kind of leaks. The fuel system carries approximately forty to fifty pounds of fuel pressure. If there are any flaws in the integrity, you'll notice it. There will be fuel spraying. I'm going to step over here into the passenger compartment. Like I said, just cycle the key several times. Once we've cycled it several times, you're going to go ahead and take a look where we made our connections for our filter. No leaks here and no drips coming from the inlet side. We're okay to go ahead and fire the engine.
