no reason to buy a Walbro 255L anymore
Buy this instead

Probably the same pump that Deatchwerks is rebadging.

Well, it's 385lph pump. This would be about 35% more than the 255lph pump. I would guess (since we know the 255 is maxed out at 550whp on a DJ) that this pump should do about 700whp.
Hence my post about maxing out a Stage 1 blocks

From my pump supplier:
" Walbro does not make a 385 lph pump, I just got off the phone with Walbro and they are working on a 325lph pump but it will not be available as a pump by itself until Late March"
So, it sounds like a mistake was made on that site.
Even at 325lph, it would still be good (in theory) for mid 600whp.

I don't think this is a Walbro pump. DW has a prototype in the works that we're about to test for them. Stayed tuned.
Also keep in mind, these very high flow pumps should only be used with return fuel systems, until someone tests base fuel pressure with the OEM returnless assembly. That little hole that is drilled into the OEM FPR will likely have to be larger, in order to maintain a reasonable base fuel pressure.

Ya other platforms are already investigating this pump. I also read that it uses much bigger fuel connections compared to the 255. Also read that its the pump used in supercharged LS9 applications. 
Although it does seem to be stamped with the standard GSS341
The DW pump will be priced similiar (~$175) and flow similar to the bosch 044. If that walbro is shown to flow 385l at 110$ its a no brainer. The supra and DSM guys are on it and they try new things, so it wont be long til more info is available.
I just wouldnt buy a 255L until then if you have a built motor and return system
