The Ls Fuel System is one of the most vital components of any swap.
For a stock setup you need to have at least 58PSI to the rails and be able to flow 255LPH. AN (Army-Navy) fittings are a top choice when making custom lines and are primarily all I use. -6AN Lines would be the smallest I would go on a stock setup moving up to -8AN for anything up to 500HP NA.
A complete LS fuel system consists of:
-Fuel Pump: Either internal or external minimum 255lph/60psi
-Fuel Line: I prefer AN Lines to rubber hose
-Regulator: If using stock intake verify if you have a
--Return style fuel rail (Inlet and return line on intake) or Returnless Style (only one line on intake). For return style no regulator needed for stock - mild applications.
--Returnless requires external regulator.
-Fuel Filter: any basic filter will do, preferably something that can be easily replaced
-Fuel Rail Adapters: If using stock fuel rail these will convert the push to connect fittings to AN
Bare Minimum for a stock setup 255lph/60psi

Autozone PFS Gasoline Fuel Pump 5211005: 47.99

AN-6 Hose Kit
Basic Generic Kit:
Includes an assortment of fittings and 20ft of hose this is my preferred kit.
Fuel Injection Hose Clamps
These are great clamps to use instead of regular hose clamps, mainly used for clamping the AN hose onto existing barbs such as those on stock fuel tanks.
AN-6 Fuel Filter
This is a very good cheap replaceable fuel filter, it comes with multiple size AN fittings and a nice bracket.
Fuel Filter Mount
Incase you need one
Push to connect - AN6 Adapter Fittings
You will need a external regulator if you are using a returnless fuel rail this is a good OEM style filter/regulator combo. It includes AN adapters as well.
Fuel Tank Return Bulkhead Fitting
If you are using a fuel tank that doesn't have a return line you can use this to add one
OEM Spark plugs
