![]() Where is the fuel regulator? I have search up and down and cannot find the regulator. where do I go from here and what could be the issue here. which is a different question all in itself. Only other issue is small antifreeze leak where quick connect on hose connects to front heater core. if engine is running and I press on needle of valve, gas shoots out. if I remove pressure guage, shut engine off and push in on the schrader valve needle, no gas at all comes out. shut it off, pressure starts dropping toward zero. when I hook vacuum back up, pressure drops to 35 and stays as longs as expedition is running. if I remove vacuum from fuel regulator, pressure jumps to 45 psi and stays. if I hit gas fast and hard, pressure jumps to 40 psi then falls back to 35. no leaks in pressure guage setup.If I start the suv, pressure jumps to 35 psi and maintains. it then starts to drop at a steady slow pace all the way back to zero. ![]() I turn key to on position and pressure jumps to 35 psi. after that, runs like a new one all day.Īfter sitting all night, I hooked fuel pressure guage up to schrader valve on fuel rail (which I am assuming is the schrader valve on passenger side fuel rail) and pressure reads zero. it runs rough and idles up and down for nomore then 20-30 seconds. Symptoms: on first start of the day after sitting all night, it starts after 5 seconds or so of cranking. ![]() ***please help**first I want to thank everyone in advance for their advice.Ģ001 expedition 5.4L engine eddie bauer with 94k miles
