Here are the specifications for a 2003 Ford Expedition according to the Ford Service Manual: - 4.6L 2V Key on, Engine Off (50 psi) - 4.6L 2V Engine Running (50 psi) -5.4L 2V Key On, Engine Off (55 psi) -5.4L 2V Engine Running (55 psi) - 5.4L 4V Key on, Engine Off (35-45 psi) - 5.4L 4V Engine Running (28-45 psi)
So in your case, is the car good? 14psi engine off/50ish psi engine on? I'm asking because the 4.6 says 50/50 for both on your comment. I got a 5.4 and it was 35psi for me with the key on but not running. I turned the key (didn't run the engine) back and forth a couple of times and eventually it went up to 50psi. With the engine running it went to 55psi. So 50/55 with on/running. The 2nd time I ran it it went straight to 50psi without me turning the key back and forth a few times. And 55psi with the engine running. I was wondering if that means I'm good and my issue is another part. Thanks! Hopefully that makes sense.
@@josegomez6549My fuel pump was actually going bad when I made this video. It ended up going completely out several weeks later. I did a video on diagnosing and replacing it. Your 50/55 measurements look pretty close to specs. I'd probably try to raise the RPM of the engine with it running to see if the pressure drops at all. If it drops, this could be signs of a weak or failing pump that can't keep up with the additional engine demand.
The adapter that allows you to go from the gauge to the Schrader valve usually comes with the fuel gauge kit. Here’s a kit the comes with the adapter: amzn.to/3SPi9CL
The purpose of the adapter isn’t to activate the Schrader valve. The adapter just allows the gauge to be connected to the Schrader valve. The Schrader valve is a spring-loaded valve (similar to valve stem on a tire). It has a central pin that, when depressed, opens the valve and allows the fuel (or air) to escape. When the pin is released, the spring pushes it back into place, sealing the valve and preventing fuel from leaking out.
Your Ford Expedition is a 2nd Generation (U222) like mine. Here are the specifications for a 2003 Ford Expedition according to the Ford Service Manual: - 4.6L 2V Key on, Engine Off (50 psi) - 4.6L 2V Engine Running (50 psi) - 5.4L 2V Key On, Engine Off (55 psi) - 5.4L 2V Engine Running (55 psi) - 5.4L 4V Key on, Engine Off (35-45 psi) - 5.4L 4V Engine Running (28-45 psi)
A couple places you can check....1) Owner's Manual - the owner's manual will often provide detailed information about the engine, including the number of valves per cylinder. 2) Emissions Sticker - Under the hood, there is often an emissions sticker that lists the engine type and other relevant details. 3) Engine Code: The eighth digit of your VIN should indicate the engine type. Hope this helps.

My pleasure. Appreciate you!
I enjoyed the video, very well done thank you 👍
My pleasure! Thanks a bunch for stopping by the channel.
Good video. And BTW thats a good vehicle.
Thanks!
How much you charge to do mines? I hate working on cars.
Hi bro, what is the name of the adapter schrader? I need it, thank u
The adapter that allows you to go from the gauge to the Schrader valve usually comes with the fuel gauge kit. Here’s a kit the comes with the adapter: amzn.to/3SPi9CL
I got that same kit but the adapter doesn’t actuate the Schrader valve.
The adapter doesn’t activate the Schrader valve !!! What part do I need????
The purpose of the adapter isn’t to activate the Schrader valve. The adapter just allows the gauge to be connected to the Schrader valve.

How do I know if I have the 2v or 4v on the 5.4?
A couple places you can check....1) Owner's Manual - the owner's manual will often provide detailed information about the engine, including the number of valves per cylinder. 2) Emissions Sticker - Under the hood, there is often an emissions sticker that lists the engine type and other relevant details. 3) Engine Code: The eighth digit of your VIN should indicate the engine type.

What is the other (clear) line connected to?
The clear line is for discharging the fuel when pressure is released from the gauge. Remember to release the pressure before removing the gauge.
would have loved to know what the specs were suposed to be on this engine 80lbs 10lbs who knows ?
The fuel pressure specifications are pinned in the comment up above. They were taken from the Ford Service Manual. Thanks for the feedback.
