Need help with fuel pressure test

Hi All, new to the forum, but not to working on cars.

I have a 2004 Anniversary Edition 3.8L 5spd, and I'm having some trouble with it. I wanted to test fuel pressure, because the car is bogging down when taking off from a stop. You literally have to just push the gas and pray it doesn't stall out before it begins to accelerate. I rented a tester thinking I could at least rule out the pump and filter instead of just throwing parts at it, but instead of having a fuel pressure test valve, there is only a Fuel rail pressure switch. I thought maybe underneath it would be a valve to connect the fuel pressure gauge, but it's just a smooth hole with no valve or threads.

I'm wondering if there is a separate adapter I need to find or a different place to measure the pressure manually. Or maybe someone has had a similar issue with their car, and knows something better to start with.

I have recently replaced the plugs and wires, air filter, belts and hoses for maintenance, but this problem is getting worse. I also had to replace the linkage rod bushings for the IMRC. Maybe it's stuck closed, but how do I tell? I don't have a scan tool. I bought a USB cable to connect to the OBDII connector, but haven't found any affordable SW to use it with. The seller screwed me over and never sent the code for the SW.

Anyway, enough rambling. Thanks in advance!

 

Thanks for the reply MustangDude.

I found that thread too, but he never says where it is. I messaged him, but no reply yet. Not holding my breath, as his last time on the forum was 2013.

I know everyone says it’s supposed to be on the front of the rail on the driver side, but mine has a Fuel Rail Pressure Switch located there, not a Schraeder valve. I’m wondering if there is an adapter that is fitted between the switch and the rail that has a connection for the manual pressure gauge or something.

If not how could you check it manually? All the lines are hard plastic with fuel line fittings. No rubber or hose clamps to put the tester in-line.

I guess Ford just expects us to trust the switch will never fail?

 

I saw that video on you tube as well, but couldn't tell what he had it connected to. There’s nothing there on my car. As far as I know the car is stock, so I’m not sure why this doesn't match what else is out there. This image is the bottom of the left front corner of the fuel rail, right under the fuel pressure sensor. That 90 elbow is me trying to find the right spot to take the video.

I really do appreciate the time you've taken to help me out. That cylindrical thing behind the elbow is a funnel i forgot to move out of the way before I took the video.

It just dawned on me, I think this person is using the adapter I'm wondering about.

 

I'll have to take a look at that. Unless I can find an inline adapter that will fit in between the fuel line and the rail input. Thanks for the link.
