To clarify, the older models had a return style fuel system and the FPR on the fuel rail (like yours) but at some point Ford switched to a return-less fuel system (1999?) and then the FPR is located in the fuel tank right above the fuel pump.
Also the question is, how do I check my fuel pressure without a gauge? The best way to measure fuel pressure without a gauge is to use an OBD II diagnostic scanner tool. This will give you real-time engine fuel pressure readings, directly from the fuel pressure sensor. The safest method of checking the fuel system on a vehicle these days is by using an OBD diagnostic scanner.

Where is the fuel pressure regulator on a 98 Ford Explorer?
On the ’98, the FPR should be at the right rear corner of the fuel rail, just behind, inboard and below the throttle body elbow. Only two screws and a vacuum line, no big deal.
What are the symptoms of low fuel pressure?

How do you check fuel pressure while driving?

What causes low fuel pressure?
Typical causes for low fuel pressure include a dirty fuel filter, weak pump, incorrect tank venting, restricted fuel lines, a clogged pump inlet strainer and faulty electrical control.
What should fuel pressure be at idle?
Idling you’ll be at approximately 15 ~ 20 inches of vacuum which means fuel pressure must drop by 15 ~ 20 PSI to maintain the correct pressure drop across your injectors. In other words 39 PSI base + 20 inches of vacuum at idle = 19 PSI fuel pressure at idle.
How do you check a high pressure fuel pump?
To reset the fuel light on a ford explorer you will need to access the fuel reset switch which is located in the glove box or in the foot well of the passenger seat area, press that switch and the fuel system will be reset.
