If you buy from a hose supply company all your lines are with .10 a size 
Corner cutting isnt a good idea on fuel. you can grow into it later. Pay attention to some of these manufacture websites too. They are pretty helpful if used in the right way. www.aeromotiveinc.com
Look at the EFI A-1000 setup and tell me what lines are on that system...??? Then tell me if you didnt set it up like it and then you ask yourself why peoples stuff is vapor locking, etc. Ill tell you why. It wasnt installed properly. everyone blames product quickly!!!!!!!!

I know im right. My system works FLAWLESS without a voltage regulator. Why? Because it was installed correctly with line routing, used the correct sizes where needed, and used the proper gauge wire for wiring it all up. Well gee golly, i havent had a problem. lol
Hose Supply companys are your friend.
Maganfuel makes nice y's and they are also in the $30 range and much cleaner loooking!
I never said you were wrong Mike,
ON another note, non of the people that I have read in this thread are running an A1000.
MM and myself are runnig dual intank walbros, hat are no where near -10
Im going to track down your supply company and see what they say

i think he is talking about an external pump and sump set up.. if you really want one of those for some reason and it comes with -10 fittings i guess its simpler to stick with -10 lines, i dont doubt it will work good, you just take the hit in the pocket and gain nothing
the y i posted in another thread is for inside the tank to y the pumps; not seen.

My set up was what you guys are talking about. Sump tank/-10an from tank to filter/filter hooked to the A-1000 pump/-10an line from the back to the motor to a -10 to -8 y block/-8an to each rail/-8an from the rail to the reg./-6an return to tank.
The system on the car now is a Aeromotive Pro Series pump,Pro Series filter,Pro Series reg, and billet pump controler which is all for sale.

FWIW when I ran 149mph @3780lbs I had the stock fuel filter and fuel line from the filter to the engine compartment (and then -6 to connect to the rails).
A large diameter line is needed on a carbureted low pressure system, but really isn't necessary with the high pressures that a fuel injected engine runs at.

Ed,
They even sell the fittings to go with them but they are steel. We used them on Johns wagon and it worked well, they werent as pretty as the AN stuff though. Its your call. Ive even done some Intercooler ice box lines with them and the hose. Its a matter of how pretty you want it too look but the function is damn sure the same.

Your Stock Fuel Lines cannot keep up this is the problem, not the dual Walbro 340m's 255l per hour.. I would run the braded feed like everyone here has stated, and a single setup will be fine... You could if you want to run the stock feed line back to the tank... This is the cheapest way to go about things...
Now if money is no object.. Run a Dual feed like some of the big dogs and run a braded return like everyone mentions..
I'm still running the stock fuel lines, however I'm in need of fuel here fast if I keep adding HP... My fuel pressure is Iffy as well at MAX rpms..

I am using 3/8 stainless for a feed line for my dual intank setup. Also using the 3/8 stainless tubing for the crossover. Just not sure if the tubing is going to clear the TB cable. But I have 3 different tubes bent so I can see which one clears the best. I just finished it. I will take pics when I get home this morning. Just mocked it up off a old ls1 intake we had at the shop

I have the #1 setup with 8an feed, 6an return (dual in tank). I did my setup a step at a time because I didn't want to do anything unecessary. I had drop off at WOT until I did all of it. Now if I'm messing aroung with PE vs RPM enrichment I can fatten it up and black smoke will roll out of it and fuel pressure does not move (it can really spray some fuel). I think 10an is probably overkill since some have taken stock lines to 600-800 rwhp (and the 8an is considerably larger). I don't know where the limit is with 8an but it's probably way up there.
Well I have to redo it. It wont clear with the aftercooler 
So I will do the crossover to the back and bend a 80 degree to the back of the rails with the 3/8 stainless. Just like PSJ's pic with the AN fitting. Not bad for the scrap pile and about 10 mins worth of bends. I am using all swagelok untill I get to the Speed INC fuel filter. Then I will go with the steel braided to connect the dual 255's to it. And then use the old feed as the return like everyone else. I got most of this from picking MM brain Oh yea and Inspector12 thanks for all the ideas.

WRONG you do not want to use -10 line in this setup as it is way too much feed line. You want smaller line to keep pressures up. Aeromotive is a generic company that provides that pump for several different systems. It is also used for Carbed motors at low pressures hense the needfor the -10 feed in an injected sytem at 60PSI you want the line smaller to keep that pressure up. Whats the piont of supplying high pressure and dumping it in a bucket...pressure loss. We use a Weldon pump for most of our setups and it has a -6 outlet and has feed over 900rwhp and gone 9.30's you telling me it should dump into -10 line. There is also no need to go to dual feeds and outlets for these systems.
