Will the GFB DV+ fair up any better against WMI though? I thought it was the solenoids that fail on them from memory? If so, I can't see how the DV+ will make much difference to the life of the solenoid since both use pressure equalisation to the rear of the piston to hold it closed, therefore WMI can and will get through to the rear of the piston and in to the solenoid.
