I have a Pierburg and you can bearly hear it running, it came with rubber jacket and it will easily feed my 4.8.

Either one should last you a long time. I have had no trouble with the pump I've got and it's far from Walbro quality. I think most failed pumps are caused by cavitation, running without fuel and just low down abuse. Like no pre pump filter or pick up sock. Think about the pump in the tank of your late model car...running for years.

If your tank is under the bed then you'll probably mount your pump back there somewhere. Noise probably won't be an issue. My truck's 43 years old. There's nothing quiet about it and I'm okay with that.

Looks like that one should work. Anything over 30GPH should be good. As long as it's American made. Here's a couple of websites that'll help you out with your LS1 Swap. The first site is for the TPI 305 swap and a little slow to navigate thru but when you get a chance to read it, there's a lot of good info.

A fuel pressure gauge for your engine bay wouldn't be a bad idea either since you're already running fuel lines. Good for troubleshooting and tuning later down the road.

Speedway also sells stainless. Its hard stuff! It's bullet proof however. You need a really stout flair tool to make it work. Some guys use copper flare washers in between the flares, I've seen others use compression AN- fittings as well. Make sure that aluminum line does not even THINK about touching anything without a rubber isolator. It will wear a hole through the line in no time. I'm speaking from experience.
My $.02? Stay away from aluminum.

I'm running the aluminum hard line for mine. It's not too bad, you can actually do a lot of the bending with your hands. It's easy to flare and the fittings are dirt cheap. If I were to do it again though I'd probably run push-lok. Not as fancy or durable as a metal or braided line but dam that stuff is just too easy, and good to 250 psi. As for a pump I'm runnin an Aeromotive but the dam thing cost an arm and a leg. Nice and quiet pumps though. I hear a lot of good things about the Walbro pumps, seem to last forever and deliver plenty of fuel but I haven't witnessed the noise factor myself.
