so i can basically do away with the plug on the passenger side? or does it need to stay? i have my old temp sensor cut and threaded into the passenger side head for the truck gauge. i just need to get oil pressure and then my powers to the fuses.

Is 58-60 psi the optimal fuel pressure for these engines? Doesn't need less or more? What about volume?

That is the proper fuel pressure. Your stock fuel lines are the correct size for the swap. Most of us use the vette filter/regulator and run just feed line to engine. You need a returnless style fuel rail for this setup. I left my old computer where it is.

I have the high flow fuel pump for like Camaro. back when I was running tbi. it shows 45 psi rite now. I already have the corvette regulator/filter in and plumbed up. I pretty much cut all the wires coming out of the firewall except the ac wires. im only having trouble finding the tach wire for my cluster. any idea?

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....

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?

you need the ls temp sensor for the ls ecm
