Description
GDP "Maximizer" System 07.5-09 Dodge 6.7L CumminsThe "Maximizer System" is designed to work with '07. 5 '09 6. 7L Dodge Rams with stock in tank lift pumps. We've had many requests from owners for a system to maximize the output and life of the stock in tank lift pump. The "Maximizer System" does just that! The Maximizer removes all of the restrictive factory lines and banjo fittings replacing them with custom stainless JIC adapters and full 3 8" fuel lines. No drilled out hydraulic adapters here!
The "Maximizer System" is designed to work with '07.5-'09 6.7L Dodge Rams with stock in-tank lift pumps. We've had many requests from owners for a system to maximize the output and life of the stock in-tank lift pump. The "Maximizer System" does just that! The Maximizer removes all of the restrictive factory lines and banjo fittings replacing them with custom stainless JIC adapters and full 3/8" fuel lines. No drilled out hydraulic adapters here! Factory fittings are a mere .185" diameter as opposed to the GDP stainless fittings with a full .300" diameter. That's a 250% increase in flow area through the fittings!New lines cover the connection from the factory steel supply line to the filter housing inlet and filter housing to CP-3 inlet. The stock lift pump stays in the factory location but overall pressure and flow to the CP3 is greatly increased. With a healthy in-tank lift pump, average gains above your current readings are 3 psi at idle and up to 7 additional psi at full throttle! If you're under warranty and not ready for a full fuel system upgrade, or just trying to get the most form your stock in-tank lift pump, the "Maximizer" is the best alternative available!

Secure Mount With Premium Feel
This phone mount feels incredibly sturdy once installed. No shaking or movement while driving, even on rough roads. The design looks clean and factory installed instead of bulky like a lot of other mounts. It holds the phone securely and keeps it easy to access for navigation.

Good Solid Mount
Got for my 2019 TRD Off Road. Works great, solid mount. Phone easy in, easy out once you get used to it. Looks and feels well made.

Solid Product
I was a bit skeptical based on the price ($85 total after taxes) but you can tell that for the price, this thing is sturdy and high quality. Holds solid onto the vent and keeps my iPhone in place. Easy to adjust and move to your liking, also easy to turn 90* and have your phone sideways. Only drawback is that is obstructs the view of the clock on my 4Runner and slightly obstructs my windshield, but I am sure I will get used to it.

Great phone holder
I use this phone mount in my Subaru Impreza, and it works perfectly with my vents. It holds my phone super securely—no wobbling or slipping—so it’s great for navigation or hands-free use. Really solid and reliable for the price.
