AFAKI 45 psi is way too low for the LS. That may be "high flow" for a tbi but im pretty sure its not enough for the LS. just get a stock vortec, delphi 281, or walbro 255 and your good to go. and off the top of my head, im pretty sure the tach is a white wire....
Like Tumbler in "Gone in 60" I'll drive anything with wheels or without

Tach wire is the white wire that went to your distributor.
I'm looking at the gss340 walbro 255 pump. I know there's the 340,341,342. But I figured since the 340 showed to have the largest intake on the pump it would be best. Does it matter?
