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.

bag came ripped
bag came ripped so the chewy pig ears were not chewy they were hard, I didnt even give them to my dog. The worst part is they are not returnable or refundable - what a waste of money
So not acceptable.

Awesome quality balls -- my dog loves them!
Color: F) 3-Pack (2.5" Balls)
Love this 3 ball set and variety and quality. These are the 2.5" size, similar to a tennis ball size give or take. The fun citron yellow one is the thickest + heaviest, very bouncy, and tough. The blue is still tough but not as thick or bouncy, a bit more flexible. And the clearish one is the lightest/flexible and is glow in the dark [although we haven't tried that part yet]. I have a 7month old 40lb girl who is becoming like a power chewer on some things -- but hasn't done that with these. She can play, mouth them, chew them, not even one knick or anything. Yes! The citron and blue one we leave out all the time in her little toy box. They have holes in the middle and have used them to hold thinner bully sticks and other treats. The blue one is fun to put smaller treats inside that she can work out like a puzzle. Obviously they are fun for fetch! We leave the other up and only get out when we can play with her because label said it is not a chew toy so we didn't want to take chances. Overall super fun and cool and good quality, human and dog approved LoL. ***We ordered the 2 set of 4" balls, blue and purple [they are same consistency of the blue ball] and love these too! Very fun and good at using with treats the sticks too, plus these don't get lost under sofas and furniture like the smaller ones, a big plus.

Glow and play - pups favorite!
Color: A) 2-Pack (2.5" Balls)
I can't say enough good things about this glowing fetch ball! It's perfect for outdoor play at night—my dog loves chasing it in the dark, and the bright glow keeps the fun going even after sunset. What really impresses me is the quality; this ball has withstood my pup's enthusiastic chewing (and believe me, he can demolish a regular ball in seconds). It’s durable and built to last, making it a fantastic investment for any dog owner. If you're looking for a fun nighttime activity, this glowing fetch ball is a must-have!
