buy some proper diesel rated cloth braided hose for the return lines - they are a one time fit only and will shrink themselves to the injector barbs. The last bit must be left alone or stick a bb into a piece of line to make a stopper. Change the clear fuel lines if they are now brown and brittle. The GPs are tested from the relays connector - you check each plugs resistance to ground, any open circuit is a bad plug.

The fuse you point to for the car phone installed at the dealer - you will find remains of it under the drivers seat - dont bother with the fuse, and if you do wish to add something else to the car - you can use this fuse. speaking of which, get to NAPA and order a 30A fuse strip for the blower and an 80A for the glowplug relay - theyre about 50 cents a piece, keep in the car so whenever the thing blows you have one to change immediately rather than paying 7-10 dollars at the dealer for a 50 cent part. Blower one is in the casket shaped casing ahead of the big fuse box, GP one is on the relay. Also look into buying a set of the bullet ceramic fuses for your car if yours are original grayish looking - not much money on ebay, the old corroded ones cause crazy electric problems sometimes.
