Which fuel rails? I need to order a set of LS1 fuel rails. I see them all over Ebay for under $100. Are those any good or do I need to stick with a name brand like Aeromotive or Fast?
Here are a couple of the ones I'm talking about:

Ebay is a crap shoot...
They list one rail for LS1, 2, 3, 6, 7 & 9... but there are about 6 different variations depending on the injector & intake combo.
The one link you posted, shows the machining of the o-ring grooves & they look horrible. They should be smooth, not full of chatter marks.
Also connection type varies. O-ring being the best & pipe thread less desirable.
Extrusions are more likely to crack, but cheap.
Personally I would not use these rails, even if given to me.
It is all in what you want.
I offer a billet rail, but it is much more expensive than the $99 rails you linked to.

Ive used the speed inc cheapo rails for years without issue
Use NPT fittings with teflon tape and tighten until you cant hold it with your hand. Do not put it in a vice and torque the snot out it or the ends will split which is why most people talk bad about them
In general LSx fuel rails are pretty universal
Worst case scenario you'll have to swap the upper injectors O-rings for a different bore ($8) or cut/bend up some scrap alum for new mounts. Depends what you want to do
