"The good thing about cars with points is they typically give warning when they need servicing" - The bad thing about points is that they don't run if the car has been laid up for long periods of time. The points, when not used for extended periods tend to film over to the point of not conducting. No warning, the pump just won't start up. If the car is driven on a regular basis and the rebuild is done correctly and adjusted correctly, a points style fuel pump will last somewhere around 75,000 - 100,000 miles or more. An all electronic pump should last considerably longer, theoretically until the diaphragm ruptures or gets too stiff to pump the fuel. The electronic circuit should last even longer unless the inlet side of the system gets clogged up with rust from a tank that is not properly sealed. If that happens, then in addition to burning the internal swamping resistor in the coil housing, the electronic circuit board can be damaged also. Bottom line, keep an eye onthe fuel system regardles of which type of pump you have installed (including any of those "super reliable" after market pumps we keep hearing about) and fix things before the "things" fix your pump in ways not acceptable to you.
