Blue Spring install into my 04 Ford F-350 6.0

Installed a Sinister Diesel blue spring kit on my 04 Ford F-350 6.0l. I was quoted $90.00 plus parts but saw other videos and decided to tackle it myself. Huge difference in the way the truck feels now and better power when it's cold. I noticed better acceleration when cold and of course no more leaky fuel filter. Definitely something you can tackler yourself. I got the kit from Sinister directly and was around $65.00.

I have a question. Did you ever have to adjust anything or was your fuel pressure where it was supposed to be.

[@BenitoGuerrero]

Nothing to adjust. Evidently the spring is stiffer than what came from the factory and that is what causes the fuel pump to build up pressure and give you a bump in fuel pressure.

Did you experience any leaking from the fpr? I’ve heard reports of it but I wondered if you have experienced it

[@BenitoGuerrero]

So far I have no leaks. I've checked it a few times while running that I had even a small leak.

@@BenitoGuerrero thanks! Great to know

Didn’t put the o ring on the black plunger piece

I tried to install one but it didn't fit and there wasn't one when I took it apart. Haven't had any issues
