The easy 30 minute install of the new updated "Blue Spring" will increase your fuel pressure back up to where it should be from the factory. Most 6.0's see an increase of 10 psi of fuel pressure. The added fuel pressure will help keep the injectors from outflowing the stock fuel pump, meaning no air in the injectors, and an injector that will live much longer. Most trucks will actually quiet down a little at idle, rev up a lot quicker and with the added fuel pressure, a little quicker spool up on the turbo. The kit does include all the O-Rings and hard parts to rebuild the fuel pressure housing. Another major bonus is that this block has an adjuster screw in it. This will allow you to bump pressure up a little for big injectors. Or after the spring settles after years of abuse, just loosen up the jam nut, and run the adjuster screw in a turn or two to get your fuel pressure back to where you want it. Everybody has their own opinion of fuel pressure in a 6.0L Powerstroke, why not choose for yourself, we recommend setting it between 55-68psi. This kit also comes with a Brand New Billet Aluminum housing to keep the regulator spring set and to prevent leaks from the housing. This is a much thicker, stronger billet piece than the factory Cast Aluminum spring housing. The factory unit is known to leak or "weep" fuel from the sides. This kit will also help clean up the look of the factory filter housing as well., Note: NOT Compatible with E-series., Features:Anodized in Sinister Blue, CNC Machined from T6-6061 billet aluminum, Laster etched Sinister Diesel logo, New "Blue Spring", New Gaskets, Adjustable fuel pressure so you can fine tune your performance, Restores lost fuel pressure from a worn spring, Helps save Injectors from low fuel pressureIncludes:(1) Sinister Diesel Billet Spring Housing, (1) New "Blue Spring", (1) New Gasket/O-ring set, Installation Hardware.

Lovely
Format: Kindle
Lovely and sweet. He falls first & the yearning is perfect. Slow burn, but sexy. Both main characters were relatable and likable.

Letdown after ESA & OGS but Still a Great Summer Read
Format: Hardcover
Highly anticipated after 2025's One Golden Summer sequel to Every Summer After because The Florek boys are everything. Loved the setting (Tofino sounds gorgeous), but the book was off balance. Long-suffering George was so thoughtful & obviously in love with his BFF Frankie. Other than shared history, I wondered why. She's supposed to be independent (as was Jo in her fave book Little Women), but she spends a lot of time sobbing, moping, resenting, & pushing everyone away. She's oblivious to George's obvious devotion even when he's traveling the world for work & firmly consigns him to the friend zone (but doesn't date anyone else beyond a device driven brief engagement to wildly unsuitable guy). At 30, she still thinks romance will kill their 22 yr friendship? Even their magical week in Tofino when they're together is unsettled by her reticence & constant disbelief they can be a couple. There are a lot of flashbacks to the besties at 8, 12, 16, 20, & last year that disrupt the flow & don't serve the story. Still, she writes beautiful sentences and has the ability to transport. It's a good book, just a 4 not a 5.

George was awesome...the setting was beautiful...not a fan of Frankie
Format: Hardcover
I had to buy this book since One Golden Summer was amazing and stayed with me longer after I finished it. In this book, the setting and descriptive scenery of their honeymoon destination and how it was woven into the story was the highlight. The romance took second place and was lackluster overall as I never really connected with why Frankie was such a good friend and George fell in love with her. The ending was just okay and I think the letters could have been better utilized in the story instead of dumped in at the end. The whale storyline was a footnote and distracted from the story. It could have been a few chapters shorter overall. I loved George and felt like he deserved better.

predictable but enjoyable
Format: Kindle
Very obvious plot, but still enjoyed the character and storyline development. If you’re looking for a mindless, easy romance then I would recommend this.
