Fuel pressure

Having an issue. I can't find my schrader valve (the fitter where you hook up a gauge to check fuel pressure) in my engine bay. I have 4.0 SOHC. Can anyone help? Post pictures if you can please.

What year truck? My 2005 4.0 has a schrader with a blue cap on the end of the fuel rail (toward cab) on the passenger side. It's kind of hard to see but if you push some of the wire bundles aside and feel around you should be able to find it.

Welcome to the forum

Yes, +1, early 4.0l SOHC Rangers 2001 to about 2003 didn't have schrader valve

You can test pressure at the fuel filter if you make an adapter
