Alrighty so i'm going to put in an order for fuel parts and this is whta I have so far:
1987 R10 Fuel Tank
1987 Fuel sending unit
Walboro 255 gss342 fuel pump
3/8 to -6AN QD is Russell 644123 (feed)
5/16 to -6AN QD is Russell 640863 (return)
Fragola Hose assemble AT165056ERL (hardline to rail feed)
TBI truck fuel filter(dont have PN yet, if anyone would suggest one)
2 of the AT991955ERL fittings to adapt it from 16mm o-ring to -AN

And I believe my truck doesn't have a return line but I'll check tonight.
Again, Thanks a lot everyone!

Heres what my list looked like.
#'s 1 & 2 look good on your list, my truck was an 87 so I already had them.
#3- AC Delco EP381
#4- 3/8 compression to -6an (SU feed)
#5- 5/16 compression to -6an (SU return)
#6- 20' of 3/8 (-6) stainless fuel line
#7- 3/8 gm quick disconnect to -6an fitting (ls fuel rail supply)
#8- 5/16 gm quick disconnect to -6an fitting (ls fuel rail return)
#9- 6, -6an straight fittings
#10 inline high pressure fuel filter

You want an AC Delco EP381 for a fuel pump, not the walboro you have listed. These can be had for $25 or so. Is what I used and WILL mount up to your sending unit like factory.
Better off in the long run to convert to AN fuel lines.
