anyone who has tried the mr. gasket pump has posted with bad results and short life.

personally, i have an airtex pump set up in an unusual way: its in line with the mechanical lift pump (which is less than a year old), and is wired to only run when the glow plugs are on, making it a starting aid only, for when i have air in the lines. for only running 15 seconds at a time a couple times a day, it'll last forever i'm sure.
for doing it this way, i still use the mechanical pump i just bought last year, but have a backup for starting with air intrusion, and in the event of the mechanical pump failing, i just have to bypass it and change one wire on my e-pump, and i'm back on the road. i see it as the best of both worlds, others here see it as a pointless system. you decide for your truck.
as you know, most guys who do it remove/bypass the original lift pump and have the e-pump wired up so it has power whenever the fuel solenoid on the IP has power
