As long as the pump is in good condition it should push fuel to the mechanical just fine.

 

If it's working it will probably do just fine. When they cut out, however, the engine keeps running just on the mechanical. You have to make sure it's actually getting voltage and actually pushing fuel. Not easy to tell when they die.
