What micron does it filter
You're still flowing fuel through the stock 3/8" port. Will that still be a restriction even with a bigger line? [MENTION=26740]Jn2[/MENTION] did you use this adapter or did you remove it and go all AN from the stock pumps? I was thinking about getting rails w/crossover and just feeding in one rail and out the other versus a Y into each rail, and then each rail into the regulator. I'm just wondering how much more power the bigger feed line/rails will be able to support without upgrading my injectors from 1050x to 1300. [MENTION=17656]higdominator[/MENTION] was leaning out around 7500 at 850rwhp and I believe running the stock feed line through DW95's IIRC.
You could do that, it wouldn't be hard at all to drill out the hat and add a bulk head fitting in order to go with larger lines. Once this kit gets out I am actually planning on upgrading those GT350 pumps to the new DW400's(which flow 31% more than the Walboro 455's) to help support 1kwhp+ on e85 on a dual set up....but this won't be ti'll later on(if ever)
I have to ask why Sai would not stand behind his pumps if we added a inline filter ? If the GT350 uses a inline filter and we are using GT350 pumps I can't see why that would be a problem ..

Would that 3/8" output from the stock hat still be a restriction though? The 3/8 to AN adapter almost seems too easy. I still have my original single pump/hat assembly in the garage, so I'll take a look at that one.
Bulkhead for the feed, on the tank side you route it to the 2 pumps, on the top you route a single line to your rails. Again, only a idea in my head right now, might never come to fruition
I'd like to see how limiting the 3/8 line really is, because that's what everyone says is the limiting factor. Some say you just need bigger injectors. Only way to really find out is to try it I guess. Maybe someone who's starting to run out of fuel up top can try a new feed line with rails and tell us how it changes. haha. I already have a Sai kit and was looking to upgrade my feed line and rails, and go true return to help with vapor lock. And at some point I may need more fuel. Not sure how these 350 pumps do at higher base pressures.
Ask and you shall receive, also I might offer a upgrade kit for you to replace your feed line with a 8AN line and include billet rails, thinking somewhere around $350...this would let you go true return so you won't have to worry about vapor lock
no, larger lines create less friction, less friction = less pressure drop acrcoss the an identical lenght of hose(6an vs 8an). The flow gains would be minimal, on a high pressure EFI system, pressure drop across hose is a lot smaller than it is on a low pressure carb set up. So IF you are only be seeing a 3psi drop on 6AN that is maybe 1.5-2psi on 8AN, you would then need to refer to the pumps flow chart and see how much more flow the 1-1.5psi you just saved will give you. Chances are it's a negligible amount.
