It's always a good idea to upgrade the in-tank pickup if you are upgrading the supply line. 3/8 stainless supply line is an excellent upgrade for a 1st Gen. Never worry about it again. But the pickup pulls through a little plastic widget in the bottom the basket that goes through a "less than" 5/16 hole, probably 9/32. So unless you get in there, drill that out a bit and add a 3/8" connection to the bulkhead on the sender top you will not gain any benefit from the larger supply line.
I laugh sometimes reading the posts on various forums about guys that have half inch fuel lines and big pumps but can still "pull it down to zero psi."
Ya think?

Ok, so looking at it, I should just drill out the top of the module, and thread in a 3/8" barbed 90* fitting, right? I think I will seal it up with some JB weld (doesn't need to be pretty). Then run 3/8" line down to the pickup.
Thing is... I think I am missing a few pieces on the pickup
anyone got a pic of what a complete one should look like?

No. You need to pull the entire pickup/sending unit and mod the pickup inside of it. This involves installing a bulkhead-type fitting in top like you mentioned and replacing the inside portion of the tubing that runs down to the actual pickup itself in the bottom of the basket. That tubing connects to a plastic piece that the fuel enters into (the actual fuel pickup itself). This piece must be drilled out. Very carefully. I believe I actually used the drill bit clamped in a set of vice grips and a dremel tool to finish it up and avoid damaging the pickup. It's just plastic.

Make sure whatever you do inside the sending unit is not going to be able to work it's way loose and eventually come apart over time. That happens and it's game over wherever you may be. Diesel-compatible fuel line. I used red loctite on the tubing clamps and let them dry for about two days while I was working on other stuff. Constant-tension spring clamps would probably have been even better.
These things may be obvious to some, but like you said...
