As time as gone on, these newer electronic pumps are not as expensive as they once were when they came out 20 yrs ago. Even the pump on my colorado diesel is only 500 bucks brand new from the dealer. Considering the thar has been around for awhile running this setup it might even be cheaper to replace the electronic one now as opposed to the mechanical one. All mechanical is cool and has its advantages but I think it isn't feasible now. The electronic ones last awhile now.
