Fuel pressure 6.0?

[Lonno]

Anyone know what the fuel pressure is on the pressure side of the frame rail fuel pump? How many psi's am I looking at.
Thanks,
Dave

When I had my 6.0, I tapped a fuel pressure guage into a banjo bolt on the secondary fuel filter and it read like 26-30 psi i wanna say.

Thanks bud, I think that would be the very low end. I think its more like 50-55#'s. Not sure tho.

Final bump for a little help.

I was told around 52-55#s also.

Thats Pain. Cool, I just wanted some sort of confirmation.

Sounds about right, Dave.

thats at idle, but when on the throttle really hard i think it can be as low as 45psi

Anything below 40psi is killing your injectors. 50-55 is ideal. also remember....it's not always about pressure it's also about volume. Raising the pressure demanded of a pump can also severly lower the volume it can put out. You can have the pressure and still be starving your injectors for fuel.
