Fuel pressure

[lildon69]

I have a 2010 F-150 with a 5.4 flex-fuel. Do anyone know the fuel pressure?

Did you check the owners manual? Might be in there. But hold on I'll see if I can find it.

Not too sure about this, but it should be around 25-30psi, that's the norm I believe, but you have the E85 engine correct, that is the Flex Fuel one. Just a friendly suggestion too, but next time post questions about engine stuff in the engine section, you'll probably get a faster/more accurate response. I hope this was of help however. Come back if you have anymore questions!

normal operating range is anywhere from 35-42psi with a return system

I've said it before and I'll say it again, you need an app so I have a quick reference guide lol. You're knowledge of everything cars amazes me.

Amazes u? It's amazing how one person can possess all that knowledge. Lol. And b spot on everytime. Go alex

Ryan, your answer was spot on. Fuel pumps rarely put out minimal pressure...they either run or they dont. If you're getting ~30psi, you're good. If its like 10-15...thats a problem (which might not be a pump problem).
