Most trucks will actually quite 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.
This kit also comes with a Brand New Billet Aluminum housing to keep the regulator sprig 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.

Long lasting ducks
Color: Crinkle Duck (Yellow), Size: Large
My dog hasn’t ripped this one open and she enjoys the crinkle. The squeaker has stopped, but it still has crinkle. It’s also really easy to clean. She has 3 in total.

Monkee-doodle loves that it has a crinkle sound when playing tug-of -war
Color: Crinkle Chicken (Yellow), Size: Large
Monkee-doodle likes this toy because it has a squeaker and it also has a crinkle noise maker inside. She loves playing with the toy and it’s easy to spot since it is bright yellow in color. It is suitable for dogs and doesn’t have any pieces that can come loose and harm your pet.

Perfect for a loved pet
Color: Clemson Tigers, Size: Small
This is a soft material. Runs a bit bigger but that even better when it comes to a fat belly pup. The price is great. Quality is great too

Went with large, he weighs 25 lbs
Color: Ohio State Buckeyes, Size: Large
This is so cute and fits well. Our little guy weight 25 lbs and I went with size L. I like that it’s thin and can be worn around the house. Since it doesn’t fit skin tight he doesn’t mind wearing it. Keeps him a little warm too. Washes up nicely with no shrinkage.
