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.

Good, but use batteries
These work good, very bright lights. But I wish I would have gotten the solar ones. These take batteries and I don't want to keep buying batteries.

new fav
Size: 6.8 Fl Oz (Pack of 1)
i’m always really skeptical of trying new face washes but I do love this brand and I’ve been using their lotions forever. It’s the only thing that keeps me hydrated so I thought I would give this a try I do have pretty dry skin so if I use that product alone with no moisturizer, of course I’m going to be dry, but with this wash and their lotion that I use, my skin is hydrated, I am not breaking out. This is definitely become a favorite for me, I do wear a little bit of makeup, but I haven’t tested if the wash itself takes off all the makeup I use their micellar water and then I use the cleanser and that works great!! even with that double cleanse as long as I’m using that lotion, my skin is not dry at all. I have noticed my makeup goes on smoother and I’m hydrated through these winter months. the gel texture is different, but it feels nice on the skin for me It doesn’t feel like you have to keep washing to get it off. A little goes a long way and I wouldn’t really say there is a scent to it but it’s just a very clean smell

The best face wash for extremely dry face!
Size: 6.8 Fl Oz (Pack of 1)
Best facial cleanser for very dry face. I use tretinoin and have very dry peeling face at times, that can be unbearable. I've tried nearly every brand of face wash and type. This is the best!!!! It leaves my face silky smooth, helps get all the dead skin off and lessens to eliminates my itch. I mean it when I say it's wonderful!
