fuel system help I need to know what fuel system to go with for my car?
mods:jet-hot LTs, catless y pipe, slp LM, D1-SC@8psi, TR 224/227@114lsa
I was thinking of going with the SVO 42# and the racetronix 255 pnp pump, maybe even some fuel rails.

8 psi? Stock fuel rails will do the job fine... Unless you have plans to do much more later? The 42's might be pushed too far if you ever increase the boost by not really that much I think. BTW that set-up must sound like a beast.

I had almost the exact same setup on my previous car (used to post as ws6horsepower) but had 38lb injectors and inline pump. I was running out of fuel at ~6000 rpm (pressure dropping to 51psi and injectors open full).
If you are handy you can wire the intank yourself, it is pretty simple (I did my duel setup).
If your target is ~450-500rwhp 42lb and intank walbro 255HP will do the job.
If you want room to grow ~550-600rwhp+ go with 60lb and duel intank walbro 255HP.
Leave the fuel rails alone, they will be fine.

TondSS Ebay.....MOST sponsors....Summit.....Jegs all sell Walbro pumps in 1 for or another.You but 2 of them and use a Y fitting to connect them to 1 feed line.
ARD Id personally do 60#ers if i were u so u have a bit of a cushion to grow a bit....or 42#ers and a boost referenced duel pressure regulator to raise the fuel pressure so the injectors wont work as hard.And 600rwhp is about the limit of the stock rails so anything above that and you have to upgrade.Since you already have a pump use that and get the FPR.
