I had lots of fuel issues since I got the kraftwerks kit ..started with that grams pump that came with kit ..it kept cutting out on me .. Went to fullblown 340 with sos wire kit..still same crap ..talked to Evans tuning and he said the full blown was my issue ..he swears by the walbro 255 and is all he uses with fi cars ... I installed it and no issues since .. Just a heads up so you don't have to do this job 3times like I did .. And always use oem fuel sock it fits perfect in the bottom of the gas tank ..

 

First ive heard of a problem with a FB340, I think your case would be the exception. Ive had mine for 5-6 years now and over 100k miles. Still going strong. I think its probably taken over as the most popular alternative to the old noisy smaller capacity Walboro 255. I have heard of some issues with the Aromotive 340 however. The first Walboro I got was no good, ended up being counterfeit I was told. One thing that hasn't come up with the FB yet as far as I know. The second 255 I got was fine and used for a couple years, but the noise got to me.

 

I installed a Walbro 255 in 2007 and it was so noisy that I bought an Aeromotive 340 less than a month later. I've had it since then with no issues whatsoever. I'd do it again.

 

My DW300 has been awesome!

 

Are the Walbro 450's noisy?

 

The walbro 450 is quiet. You do need to wire it up with a relay.

 

LEGEND. Cheers!

 

Lol! Let me know if you need anything brother.

 

I've got a walbro 255 on standard car, it whines when it gets hot but meh its not that bad!
