fuel pressure

I have a 2000 f250 7.3 and I was wondering sometimes my fuel presuure is running 75-80 psi is that too high? And if it is is it hurting anything?

that is too high.
could damage the pump, seals etc.

ideal is between 60-70

is this fuel pressure at idle or WOT?

what did you do to achieve higher fuel pressure?

with the stock fuel pressure spring in it usually holds at 60 idle then drops to 50 at WOT.

What are you monitoring fuel pressure with?

80psi is too high, and the main cause for concern is leaks.

I get 80-90 at idle and have for 5 years with a stock pump, no leaks. I put a gauge in an old filter cap, how else are you supposed to read fuel psi?

Most people remove the plug on the back/left of the fuel bowl and run it from there.
If you run a gauge into the cab you can see what it's doing in. Conditions other than idle.

Are you sure that the gauge you're using is accurate? Because not only is 80 psi too high, it's nearly impossible for it to be that high if the system is in fact stock.

Still pretty slow, just less slow now.

I once did the bb mod, but I'm pretty sure I removed it later on cuz it didn't change the fuel psi, all I know is it doesn't leak and my truck is quieter than any other 7.3 I've seen, besides that four inch gaping hole coming out my tail pipe
