I am wondering if I should stick with the stock fuel line or go with stainless braided -8 AN for the full length.
I am going to be using two walbro 255's in the tank with the dual pump hanger. One pump will be on all the time while the other one will be controlled by the boost level. I am going to use a splitter on the engine side and run dual feed to the front and rear of the fuel rail with the return and FPR coming out of the cold start injector hole.
I am hoping for around 550hp on race gas, and somewhere around 450ish hp on 93 octane. A "simple" mod list; GT3582R, 680cc injectors, Maft-pro, probe .020 pistons, eagle rods, 1mm oversize valves dual springs, 264 BC cams, ffim, ect, ect.
I am kinda on the edge about using the stock line thinking it might be to small, if someone could give me a better idea if it will be enough that would be great. Thanks in advance.

why dual pumps? why not a single, avoid the possible problem of having a pump fail and then have major failure. braided line is gonna cost to, but in the end it will be worth it. i personally am running a full aeromotive setup a1000, pre-filter,filter, and fpr. i run -10 line from tank to bay, then it splits from the bay to dual -8 with a -6 return. sweet i know :p but very spendy. but with braided line it will be nice to have in the end for any future upgrades.

Well the dual pumps is because I really dont want to sump my tank. I have looked at the a1000 and comparitavely price-wise it makes sense to go with it, more flow for about the same price as the dual hanger and pumps, I just dont want to have to do a sump on the tank. The main things that worry me with that is the clearance issue and placement of the pump. Also I remember seeing something about a type of controller for the pump to run it slower or something and then as boost increases it runs full force. Do you have yours set up at full power or are you using a controller for it? Do you think you are possibly overworking the pump at full power and not needing it, if you are running at full power? I know you said that you are running -10 line, dont you think that would be a little over kill for my goals/set up? I do see what you mean about veritility though, if I wanted to I could probably just swap out the turbo and injectors and be running a good bit more power, obviously with a new/different tune.

You dont have to sump the tank, you can always run -8 to -6y . Instead of spending alot of money on the dual hanger just run a bosh or wally inline and get it over with. With your set up you can easily push close to 600rwhp on race gas and mid 400rwhp on pump. Good luck and spend your money wisely....and -10 an is over kill for your set up :0

So are you talking about running a bosch or walbro inline with another walbro in the tank? If so wouldn't this put some sort of pull on the walbro in the tank, or possibly overwork the walbro in the tank seeing that it is constantly trying to keep up with the other pump? I dont know, I guess I am just a little confused about the inline set up and how the two pumps work together to get more flow? I guess if one pump only pumps half the distance to the front and then another pump pumps the other half the distance that would be less work on both pumps. But what about pressurizing an inline pump, are they made to be pressurized like that? Or am I completely off base with all of this? I hear you on the -10AN being a little overkill though. Thanks for all of the help.

That would be a lot cheaper and most likely lighter seeing that it is aluminum. Does anyone know how the inline pump set up would work? What about good placement under the car for the inline pump?
