Replacement Fuel Tanks

With the EFI tank kits from Tanks Inc, are fittings with braided lines used, or?

I didn't know if the connections used threads or a barb fitting

Also, I see that there are pump options......Holley Sniper and a Walbro.

Holley Sniper EFI 255 LPH Fuel pump

Walbro pumps are either 190 LPH or 255 KPH

Which is better and why?
