The stock line is closer to AN-04 than it is AN-06. If you go with FAT supply lines, you'll need to maintain volume @ pressure. So, ideally, if you're going to AN-08 supply, running 2 Walbro's will provide the same volume at pressure. And don't forget your return lines! You're pressure is dictated by the return line!

although i agree with you with what you said... how do you figure the stock line to be closer to either. a -4 is a 1/4 (or 4/16) and a -6 is a 3/8 (or 6/16) the stock like is a 5/16 (or a -5) it is directly inbetween the two. no?

as far as return goes...i am currently running -10 feed to pump. -8 from pump to rail. what would you recomend to run as the return size? i currently have a -8 return also and seems to be fine. i think it should be a -6 but i had a lot of extra -8 ss line and just went with it since i already had the right fittings. i also have the right fittings for -6... but not the line.

also, i agree with Y'ing off the delivery just for the simple reason of the stock setup has a FPD in there, and running it the way we are, the pulses from injectors upstream may cause some problems.

Well if my pump won't cut it than I will get another one. Which one should I get to support my T78 @ 24psi. Not that I plan on running that much anytime soon, but I want a pump that could do it safely. To go external I need to Sump the tank and add the pump in-line, should I move my fuel filter in-line as well when I do it?

what do you mean move your fuel filter inline? i have a filter before the pump, and after the pump. i run an aeromotive A1000.

I was talking about moving it from it fucked up location to an easier access point. Sorry, that did sound kind of off now that I re-read it. Where is yours located?

Also, how much does all this SS line and fittings cost and where do you get them? JEGS?
