I just got my Aeromotive 340 from JEGS (1142 is the model for our cars); hopefully this will help with the fuel pressure drop issues I have when I get past ~12psi...
One thing I noticed is that the voltage polarity is different on this pump vs OEM/Walbro so you'll have to solder the pump wires/connector that comes with the kit onto your fuel bucket; in the pic below the wire/connector on the left is from the OEM bucket, and on the right is the wire/connector for the Aeromotive, if you look closely on the pumps themselves you'll see the difference in polarity with the + - symbols on the pumps themselves (my iphone cam is too crappy to take those pics)
I also noticed that my OEM fuel sock is in a pretty sorry state and I don't know if I can clean it enough to my liking; can I just use the fuel sock that came with the kit, or is there a place I can get a new OEM fuel sock?
I'll hopefully install the pump this weekend and let you guys know how it goes, but the true proof is going to be when I get it tuned and if I still have fuel pressure issues at higher boost...

Got my DW today!
top to bottom: walbro, DW, oem
Trimmed the tabs at the bottom, swapped the filter bag and dropped it right in. Started up great after a few primes! initial thought is that it is a tad bit quieter than the Walbro on the first prime (key in the ignition and almost starting)

^ Beat me to it Cux350Z
I will still post my comparison
I had a extra Fuel pump assembly laying around so I decided to install my DW fuel pump that came in the mail today since everyone had questions and not many answers. I took multiple pictures from different angles so hopefully 90% of the questions will be answered. I followed the same steps Charles had written up for the Walbro installation on the CJM website there really was no extra steps needed.
The Package
The packaging
The fuel pump itself
The comparison between the DW Pump and the Walbro Pump
The Assembly
If anyone needs a Walbro hit me up, I got 2 laying around

This is a minor issue but most people will probably choose the DW pump or the Walbro because it will be one less thing for them to do or to mess up.

Dynosty has a DW301 in one of his customers cars with a turbo kit he's working on. Put down 512whp.
MA Performance has put 630awhp on their dyno using a 1st Gen DSM, DW301 (hardwired) and DW1500cc injectors running E85.
Forged put down 471awhp on their new 2011 STi on E85 using their dyno...where a Walbro 255HP maxed out around 400awhp.
Pur Performance put down 636whp on their 2010 Camaro SS with a ProCharger, using a pair of DW301s and our 65lb injectors also running E85.
Out of all of those builds, the only one using all of the pump was the MA DSM.
