Blue spring mod for 7.3L?

Has anyone done the blue spring fuel pressure mod on their 7.3l? Or is this mod only for the 6.0 I have done some searching of the forums and haven't found much.Would you recommend this mod to improve performance if it can be done to a 7.3l?

P.S If you have a ford part number that would be appreciated.

Have you or anyone you know done this mod? Which spring should I use the gold or black to increase fuel PSI and give my truck more power?

I use the gold spring , you won't notice any big difference in power, it will lift your F/P and atomize the fuel better.

If you are after more power you need other components.

Fill you signature in and we can see what mods you have already and you can be advised better.

The blue spring in the kit works to raise fuel pressure.
