I've already got a new sending unit on order (as much as I don't mind checking the level with a stick, it's not something I want to keep doing).

So, fingers crossed? Is there a chance it could be something major? If so, what other symptoms should I be looking for?
If your driving along and it just suddenly starts to spit and sputter is normally two things...fuel or ignition. In this case all your ignition components are new so there's a 99.99% chance they are fine. The fuel system however I don't recall you checking? If some crap got to the second filter I am sure the 1st is packed. That's how it was with mine. By the way, be sure to disconnect the metal line from the send unit at the tank...that helps keep the fuel from siphoning and emptying the tank when you pull a line off from underneath. lol
