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.

Great addition to the Kitchen - Not just for coffee!
Color: Black
works great for my morning coffee and can also make whip cream for those special treats!!! Cleans up easily. The recharging and attachment holder is great so you are not hunting for the attachment you need for the job.
This has been a great product and completes the task at hand very well. It has the 3 power selections for different jobs. The attachment and the base are built well and very stable.
I would order again (if need be) and I would also give a gift!

Powerful vortex of blending…
Color: Black
Too powerful!! I use a handheld frother for mixing coffee/lattes, and when my last one died, I read extensive reviews to find a new one. I liked that this one had a stand, and three speed settings seemed like plenty; unfortunately, this frother is unusable even at the lowest speed for mugs that are more than 50% full, my goodness - it created a coffee vortex with walls so high it looked like a massacre within seconds. We’re absolutely keeping it, now my husband can make whipped cream in seconds, but now I’m shopping for a weaker version, and we’ll be a two-frother household.

Love the charging stand!
Color: Black
Love that this comes on a stand instead for charging of that wobbly wire stand.
Very powerful so be careful when you’re stirring your coffee. Use it on low and keep it on the bottom of the cup.
So far it works great I bought an extra for a family member.

Works great!
Color: Black
This rechargeable milk frother works really well. I love that it comes with three detachable stainless steel whisks — it makes it easy to switch between frothing milk, mixing drinks, or lightly whisking other ingredients. The three speed settings are great depending on what you’re making, and it has plenty of power without being too noisy. The rechargeable feature is a big plus since I don’t have to keep replacing batteries and it works for many mixes before having to charge it. It’s comfortable to hold, easy to clean, and works quickly. Overall, it’s a great little kitchen tool and feels well made. I did unfortunately put the handle in my sink and it got too wet (not submerged) and did not work and I had to order another one. So be careful not to get the handle too wet.
