My advice is to get an OEM pump/sending unit from a salvage yard. The last one I got only cost about $60 and it had less than 25k miles on it. If you weld in the OEM snap-ring assembly, it makes it very easy to install/remove the whole pump/sending unit if you need to replace the pump later on.
If memory serves you have a 2001 5.3L. This will have the older style "return line" fuel system, so you will need to have that plumbed in or just get a 2000-2003 pump/sending unit.!
Oh....and never take advice from a geologist!
Does your engine have a return to it? I'd think yes but.

BTW, what IS the older style return line? What is different about that
"Older style" simply means those engines that require the use of a return line.
Prior to 2004 the Vortec and LS engines had the fuel pressure regulator positioned on the fuel rail. This location requires a return line from the fuel rail back to the tank. In the newer models the regulator is located in the tank as part of the pump/sending unit. With this configuration you do not need a return fuel line, just the pressurized and regulated from the tank to the engine.
You have a pic of the fuel rail?
There should be a main feed line to the and then the FPR I believe is run off of engine vac with a line bleeding off of it as the return.
Man, my inline pump cost me $100 and it took 20 minutes to install on my framerail and I only need a $3 filter cuz its on the inlet/suction side and doesnt need fittings to handle any pressure. Its an airtex pump that fits about 70 different fords, lincolns and mercurys.
It would take me about 10 minutes to change it out if it ever failed and would only need a screw driver and a cresent wrench.
I enjoy being able to look at my cheap clear plastic filter to see whats in it for dirt or moisture. I still have my stock 22re high pressure filter on the side of the block after the pump on the pressure side.
Thats just me tho. Cheap and simple. KISS.
