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:

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.

No white residue
Size: 3.4 Fl Oz (Pack of 1)
I put this sunscreen on immediately after it was delivered. It smells so good & goes on smoothly without any white residue. It seems to protect the skin, but then again I put some on every hour on the hour and didn't have any issues. I will be reordering. I wish this was on subscribe and save, but will continue to purchase.

Product leaks into the cap
Size: 3.4 Fl Oz (Pack of 1), Size: 3.4 Fl Oz (Pack of 1)
The packaging appears to be defective and potentially tampered with. Specifically, the nozzle is a different color from the rest of the tube—one that is not consistent with the brand’s standard packaging (I am familiar with this brand and have purchased it before). Additionally, the cap does not close properly, causing the product to leak into the lid and resulting in unnecessary waste.
This raises serious concerns about the product’s authenticity, quality control, and whether it may have been previously opened or altered.

Solid Option for a Sunscreen Spray! Nice Even Mist!
Item Package Quantity: 1
I’ve been using the Naked Sundays Hydrating Glow Mist SPF 50+ and overall I’m really impressed. One thing I was a little concerned about at first is that it does contain alcohol, so I expected it might be drying. Surprisingly, it hasn’t dried my skin out the way other similar products have, which is a big plus for me.
The scent is pleasant and not overpowering. It doesn’t have that harsh sunscreen smell that some sprays do, so it’s easy to reapply throughout the day without feeling like you’re coating yourself in fragrance.
In terms of finish, it’s not completely non greasy, but it’s also not overly heavy. I would call it slightly greasy, but noticeably less so than most sunscreen sprays I’ve tried. It gives a bit of a glow without feeling suffocating on the skin.
One of my favorite things about this product is the spray itself. The mist is very fine and even, which makes application quick and easy without leaving blotchy spots.
Overall, it’s a solid option if you want a convenient SPF mist that feels lighter than most, smells good, and doesn’t leave your skin feeling dried out.
