 C.  Replace the Electrical Bonding Jumper
 S 022-013
 (1) Remove the bonding jumper.
 (a) Keep all the parts necessary for the installation of the
 bonding jumper.
 S 422-014
 (2) For the bonding jumpers used to bond electrical equipment, follow
 the applicable installation procedure in the AMM.
 S 422-015
 (3) For the bonding jumpers used to bond mechanical equipment or tubing,
 install the new bonding jumper and hardware (SWPM 20-20-00)>
 (a) Make sure the mating surface(s) are correctly prepared.
 (b) Make sure the bonding jumper installation gives adequate
 clearance from the structure, tubing or all fuel system parts.
 NOTE: This will prevent abrasion.____
 S 282-016
 (4) Do the "Electrical Integrity Check of the Fuel System Bond Path"
 procedure.
 D.  Electrical Integrity Check of the Fuel System Bond Path
 NOTE: SWPM 20-20-00 defines the measurement processes necessary for____
 installation of electrical bonding hardware. The fuel sytem
 tubing and components often incorporate multiple electrical bonds
 in series between the component and the primary structure. The
 measurement of the tubing or component bond is a separate
 requirement.
 S 452-020
 (1) For the bonding jumper hardware installations, do the jumper
 resistance measurement for electrical integrity (SWPM 20-20-00).
