DW400 Universal In-Tank Fuel Pump by DeatschWerks (9-401-1001)DeatschWerks in-tank fuel pumps are manufactured with a quiet and reliable turbine impeller which is compatible with pulse width modulated pump drivers. These pumps are also built with carbon commutators and fully encapsulated armatures for ethanol compatibility.
DW’s high-torque motors maintain flow at higher pressure better than competitors’ pumps. Low amperage draw minimizes pump temperatures, maximizes pump life and reduces stress on OE wiring. Universal fitment kits include filter, electrical connector, and other accessories to help with installation. All DW fuel pumps are backed by a 3-year no fault warranty.
DW400 Fuel Pump Features
Turbine Impeller Compatible w/ Pulse Width Modulated Pump Drivers
Built With Carbon Commutators and Fully Encapsulated Armatures (Ethanol Compatible)
High-Torque Motors with a Low Amperage Draw
Minimizes Temperatures, Maximizes Lifespan and Reduces Stress
Includes a Universal Fitment Kit
Additional Considerations
Wiring – A 400+ LPH pump draws substantial current (16-20 amps at typical operating pressures). Make sure your chassis wiring is up to the task of delivering this much current. A DW hardwire kit (part number FPHWK) is an inexpensive insurance policy.
Size – The DW400 is a 46mm diameter pump. Standard in-tank pumps are 39mm diameter. Modifications to the fuel pump module will be necessary on some applications.
Universal Fitment – Unlike other DW in-tank pumps, The DW400 is not an application-specific fitment pump.
Check-Valve – the DW400 does not have in internal check valve. An in-line check valve may be necessary for easy engine starts in some applications.

Measure what you buy.
Size: 50 Feet, Style: 10 AWG
I love the product made my job easy on this last pontoon I worked on but the pontoons only 20 ft long and I only pulled wires halfway and I got less than 10 ft left there was not 50 ft on that spool. But now that I've cut it used it and are using it a little hard to complain, but the use of the application for the wire is 100%, thank you very much for the product.

Great value, but not overly flexible.
Size: 50 Feet, Style: 10 AWG
I used this wire to run power from my car's battery to a ham radio in my trunk, and an inverter under my driver seat. This wire fit the bill perfectly. It is water, oil resistant, and tinned (to resist corrosion). One challenge I ran into was its stiffness. Despite having many fine strands, the wire doesn't flex well. You can bend it, but wants to spring back and doesn't hold its shape. This made running the wire under the hood through the firewall, and along the door moulding... a LOT of work. I scraped a lot of knuckle in the process. Overall, I'd still recommend using it for automotive projects. It is a high quality wire. Just know that it's hard to manipulate though a lot of twists and turns.
