Sounds like a lot of trouble for a very low probability failure. But why did you install an electric pump? A rubber squeeze bulb is a better solution for priming.
An alternative to the squeeze bulb for priming, is to install one of the Racor filters equipped with the manual pump.
I agree with David, very low probablility of failure.* But you should probably have a backup manual fuel pump as a spare part.* My PO installed an electric fuel pump for priming and manual pump backup, but it has only been used for occasional priming during the past 4000 hours.* Cummins 210HP.
