I believe you have it wrong, if you tie all the dissimilar metal together then you complete the circuit, the other path is the electrolyte.

Isolating the dissimilar metals would be wiser.

Coat the pipes inside and out with black POR-15........

Solder on braided bonding straps; bond everything to chassis ground - no potential, no current flow.
