Im getting the 0191 code. I need to check fuel pressure and feel like a moron! I removed the dog house and couldnt find the schraeder valve anywhere to hook up my fuel pressure guage.on my 95 f150 its in the front driver side rail. i looked everywhere on this thing from where the feed line comes in and splits to each side. anyone know where this is located and if it has one?Also where the fuel line comes in and branches to the sides of the fuel rails is that the fuel pressure rail sensor? thanks alot !!!!
