I'm only wanting to get about 500 rwhp. Right now I'm putting down 480 rwhp on a dyno jet and 423 on a mustang dyno. @ 4800 rpm I'm running out of fuel. My tuner told me it would be best to get my tank sumped, add another walbro 255 in tank, upgrade to -8 lines and stay with the stock rails. I think I would be okay with upgrading the lines and rails. What's the opinion on this?? 
Quick rundown of what I got:
95 GT
GT40 crate motor part no. M-6007-XE FM
trick flow heads
60# inj
BBrothers turbo kit (not a bad kit for the price really)
walbro 255
walbro inline GSL392
stock lines and rails
I really don't wanna get my tank sumped if it's not necessary (which I don't think it is from what I've read here). I probably forgot some stuff but any help/opinions would be great!
