What is the fuel pressure for a 5.4 L ford expedition engine
I have a 2008 Ford Expedition and I am having problems with the engine after changing the spark plugs and fuel filter, I think the fuel pressure is too high, 60 before start and above 70 engine running. Is this normal? I can smell gas on the exhaust now. No check engine and verified the spark plugs twice.
Yes, that is high. Might need a fuel pressure regulator, or Ford calls them modulators. Specs for the 5.4 are 35 psi +/- 5
Do you know where is the fuel pressure regulator located on the truck?
35 psi +/-. You are way too high.
^ that is bso the pressure is 62-71 psi koer with a pressure of 62psi koeo
What type of gas does a v8 5.8 liter in a 2005 ford expedition with a tredtion v8
Normal regular unleaded. You could use premium if you want to spend the money but you won't get enough gain for the buck to be worth it.
