Long starts ... where to begin?

Let me preface by admitting that I am a bit of a greenhorn when it comes to working on diesels (by "a bit", I mean almost completely ).

Last year I got a new-to-me '94.5 7.3L F350 4x4 (manual everything).

Before buying it, the guy said that, other than long-cranking starts, it ran great (a "less than $5 fix").
His understanding what that there were some degraded rubber washers in the fuel pump assy that were letting the fuel lines drain back into the tank .
I gave him a week to fix it, then went to check it out.
When I got the truck, it started reliably and reasonably quickly.

A few weeks after buying it, I hooked up the 5th wheel for a little vaca.
The clutch was in less-than-new condition, but adequately functional, and we arrived without so much as a hiccup. I was very pleased.
Then ... I had to maneuver up a (fairly steep) hill in reverse to get into our spot (my first time ever reversing a big/heavy trailer up a real hill with a manual transmission) ... and quickly proceeded to completely toast the clutch

Well, after being out of commission for several months, the truck is up and driving again. We put a complete clutch kit in ... bearings, SMFW, etc.
Everything seems to be running and shifting wonderfully, but now I've gotta floor it and let it crank for a kinda long time to start it.

Is it likely that the "rubber washer" issue is back, or??
What, in your collective experience, would be your first (few) suspect(s)?

Do a quick search for starting problems. Most of them will start by telling you to check the glow plug system (relay and individual plugs), then move on to the fuel system/filter condition.

I doubt it would be a GP issue unless it ONLY happens when cold.
You need to test fuel pressure.
