Install a Corcorm brute force AC line filter as close to the motor as 
possible.  Place the motor on the load side, ground the metal case to 
the chassic, feed the 12vdc wires to the input side of the filter. 

USE EXTREME CAUTION when working in this area of the vehicle.  I suggest 
you disconnect the wire  harness from the motor, peel back the harnish a 
few feet from the gas tank and perform the filter installation away from 
the tank.


p.s. look for a second fuel pump.  Some vehicles have two.
