Been there! Try not to get too pissed off, your first fuel filter change on these engines is sort of a 'right of passage' test. Here's the 3 things to remember:

1. A new pre-filter does not come with the O-ring - it is sold separately. Don't ask me why, but without installing a new O-ring perfectly will be a large vacuum leak source.

2. In order to change the pre-filter, you will have to disturb the short fuel line from the heater to the top of the prefilter. If this line looks a little brownish, replace the whole line not just the O-rings. Trust me!

3. Fill the new spin-on filter right to the top with diesel fuel. It will save a recharge on your battery. Even with some air bubbles making their way into your fuel system, a fully topped-off spin-on filter should give you a few minutes of idling time until it starves - just enough time to look for air bubbles in the lines.

I'd also recommend replacing the fuel shut-off valve O-ring while your at it. You don't have to remove the intake manifold for this - just unbolt the windshield washer fluid bottle and push it out of the way.

If the other fuel lines look a little brown as well, go ahead and replace those too (should be less than $100). All the lines except the return back to the fuel tank can be replaced without removing the intake manifold - just unbolt the filter manifold and you should have enough room to get to the rest. The return line can probably be skipped anyway until the next fuel line replacement.
