expecting a 30 year old truck to be flawless leads to regrets

I understand that fact, my 97 is the “newest” vehicle I have owned, I have just read stories of new pumps in these installs failing and niggling problems like the last one.

Mechanical has so many potential leak points! I did larger wiring and such, so far so good after near 40k

Pretty sure Walbro had bad run of pumps as mine took a dump. Replacement is fine. TI Automotive now makes their pumps, I would be curious if all inline Bosch are Diesel rated like their 044.

But yep, after 30 years everything is questionable

Get a genuine 99-03 7.3 fuel pump and be done with it.

It will unless you're running some seriously big sticks. I'd recommend picking up the "bare" Bosch pump (the Motorcraft unit is just a rebadged version with some plastic) and buying the correct hardware for it. The assembly comes out quite a bit cheaper that way. You can even go straight to an AN fitting on the outlet (I did).
