(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.
(4)  Do the "Electrical Integrity Check of the Fuel System Bond Path" procedure.
C.  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 system 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.
(1)  
For bonding jumper hardware installations, do the resistance measurement for electrical intergrity (SWPM 20-20-00).

(2)  
For the fuel system tubing or components, do the subsequent steps:

(a)  
Measure the total resistance from the tubing or component, to the adjacent primary structure.

(b)  
Make sure the resistance is not more than 0.10 ohms.
