You dont need the draw straw (larger fuel pick up in the tank) unless the previous owner had the block mounted LP replaced with the Dodge in tank pump. If the LP is still block mounted then get an Air Dog pump or pump/filter system. They have fuel pres regulators built in and are about $100 cheeper than the FASS system. Sorry FASS, but $100 is 20 gal of fuel these days.
I run my Air Dog at 14.5 psi as set with the guage I installed right off the VP-44 inlet. I ran a grease gun hose to a T and installed the sender for the guage and an idiot light from a Freightliner ($13) as a back up to get my attention. The reason for the hose is to isolate the senders from the vibration of the engine and have them last longer. Check my pics in the gallery for details.
As stated above, you can do it for a few bucks now, or send a lot later. Other than that I don't see anything wrong with the 2000 trucks that dosen't happen with the rest. Do careful Maintenance and if it's an auto, plan on trans upgrades BEFORE going to chips/turbos/programers or you'll spend a lot of time at the shop.
