The AFE 42-12021 DFS780 Fuel System with Full-Time Operation for your 2003-2004.5 Dodge 5.9L Diesel offers you a complete fuel system solution to replacing the factory lift pump in your Ram pickup. The fuel in your truck contains contaimants, water and air/vapor which reduces power and can cause damage to your injectors. The AFE DFS780 Fuel System features a patent-pending design capable of removing power-robbing entrained air, water and contaminants. The DFS780 ensures constant availability for your CP3 injection pump, while improving throttle response and horsepower at all RPMs.
Clear High-Impact Polycarbonate Sight Glass:
Allows visual inspection of fuel.
Helical Bronze Spur Gears:
Bronze gears more forgiving of contaminants than steel gears. The Helical spur gear design runs quieter than straight cut gears.
Billet 6061-T6 Aluminum Manifold:
Eliminates porosity concerns with cast aluminum.
"Marine Grade" Motor:
Protected against dust intrusion and powerful water jets.
Horsepower & Flow:
The DFS780 can be used on a totally stock truck, it was engineered for modified vehicles. BSFC (Brake Specific Fuel Consumption) for most modern turbocharged diesel engines is about 0.36 lbs/HP/hr. Since #2 diesel weighs about 7 pounds/gallon, which gives us about 19.5 HP/gallon/hr. The DFS780 will flow enough fuel (at rated pressure) to support over 2000 HP.
Plug & Play Installation:
Supplied harness attaches directly to battery and utilizes Deutsch weather-proof connectors. No cutting or modifications of the stock fuel lines required. Vehicle can easily be returned to stock.
Relay Controlled:
The DFS780 is powered by your ignition and can be run independently or in parallel with the stock fuel pump.
PEEK Bearing Wear Surfaces:
The DFS780 spur gears ride on PEEK (Polyether Ether Ketone) bearing surfaces to reduce both noise and wear.
Contoured CNC Machining Of Manifold Passages:
Enhances flow through the manifold to reduce pressure drop due to flow restrictions.
Direct Bolt-on Steel Mounting Bracket:
Heavy duty bracket mounts to the frame and utilizes existing hole to secure.
Fuel Pressure Gauge Port:
1/8 NPT port allows customer to attach an external pressure gauge to monitor fuel pressure.
O.E Quality Seals:
Compatible with diesel and biodiesel fuels.

But this all the time
Flavor Name: Blonde, Size: 3.5 Ounce (Pack of 1)
I use this for my iced coffee. So much cheaper than buying iced coffee, tastes great, fresh, and will froth up to a mousse texture if you want to make a creama.

⭐ DaVinci Gourmet Classic White Chocolate Syrup Review
Flavor Name: White Chocolate, Size: 25.4 Fl Oz (Pack of 1)
The DaVinci Gourmet Classic White Chocolate Syrup is a must‑have if you love café‑style drinks at home. It delivers that rich, creamy white‑chocolate flavor without being overly sweet, and it blends beautifully into both hot and cold beverages. Whether you’re upgrading your morning latte or adding a touch of sweetness to desserts, this syrup is incredibly versatile and delicious.
🍫 Why This Syrup Stands Out
Smooth white‑chocolate flavor: Creamy, mellow, and perfectly balanced — not artificial or overly sugary.
Great for hot & iced drinks: Mixes easily into lattes, iced coffees, frappes, hot chocolate, and even milkshakes.
Barista‑quality texture: Silky and consistent, making it easy to drizzle, blend, or layer.
Large 25.4 oz bottle: Plenty of syrup for daily use, entertaining, or experimenting with new recipes.
Versatile beyond drinks: Works beautifully in baking, frosting, oatmeal, and dessert toppings.
☕ Perfect For
Homemade lattes and cappuccinos
Iced coffees and cold brews
White‑chocolate mochas
Dessert drizzling
Smoothies and milkshakes
Holiday drinks and creative recipes
It adds that cozy café sweetness without overpowering the drink.
🔍 Things to Keep in Mind
Because it’s a classic syrup (not a sauce), the flavor is lighter and more mixable — great for drinks, but those wanting a thick drizzle may prefer a white‑chocolate sauce.
A little goes a long way, so start with a small amount and adjust to taste.
⭐ Final Thoughts
The DaVinci Gourmet Classic White Chocolate Syrup is a creamy, smooth, and incredibly versatile addition to any coffee or dessert routine. It elevates homemade drinks with a professional touch and adds just the right amount of sweetness. If you love white‑chocolate‑flavored coffees or want a reliable syrup for everyday use, this bottle is an excellent choice.

✪ DaVinci | Gourmet Classic Vanilla Syrup: Great Flavor, Uses Cane Sugar, Great Price...
Flavor Name: Vanilla, Size: 25.4 Fl Oz (Pack of 1)
✪ DaVinci | Gourmet Classic Vanilla Syrup, 25.4 fl. oz. (Pack of 1)
_____________________________________________________________________>
♦♦ Vanilla Syrup:
● I wanted to reduce the amount of flavored coffee creamer
that I normally use, so I thought I would give DaVinci syrups
a try. This was the first time that I tried and used the DaVinci
brand.
♦♦ Coffee Time:
● I used about half of the coffee creamer that I typically use
and I added a teaspoon or two of DaVinci syrup to my morning
coffee. I gave it a good stir, then took a few sips and there was
plenty of flavor for my liking and it seemed to have a rounder
and had more of a vanilla like taste when comparing it to the
vanilla flavored coffee creamer that I normally use, I definitely
enjoyed the result.
♦♦ Great for Other Uses:
● I also tried this syrup with other drinks such as soft drinks,
cola, orange and root-beer, and a smoothie. All of them of
them were very good, indeed. Give it a try.
● I also added some to plain yogurt and some other foods and
they all tasted really good as well.
♦♦ Ingredients:
Cane Sugar, Water, Natural Vanilla Extract with Other Natural
Flavor, Sodium Benzoate and Potassium Sorbate (preservatives),
Citric Acid, Caramel Color.
✪ Pricing: $6.88 / 25.4 fl. oz.
● A very affordable price for it's size, especially when compared
to other brands that I've had before.
✪ SCORE: 5 Stars > ⭐ ⭐ ⭐ ⭐ ⭐
♦ ✪ ♦ Over-All:
● I most definitely liked the results that I got when using DaVinci
flavored syrup with my coffee, soft drinks (soda) and even food.
As affordable as it is I would recommend checking it out and see
what you can come up with. I would buy it again.
