If these pumps don't perform well without a rewire they sound like a pieces of junk considering they were supposed to outperform the walbro 255 without one in testing.

 

^this,

any new opininos on these since we are almost a year later? Quite honestly I heard alot about the DW pumps in the last couple pages. I wanna hear about the 340.

 

Search for the thread on the DW one there's a ton more info on it

 

I'm running JayRacing's 340 pump in my 2G DSM, looks like it fits VIII and IX as well :

I'm running in the mid 50lb/min range from an FP3065 on E85 with it with no appreciable signs of being out of flow. This is all on stock 2G DSM fuel lines with just a rewire. I purchased a BoostAPump for it but never got a chance to run it that way. Probably wouldn't have made much of a difference, but was there just for peace of mind.
