I got think about what you said on mechanical pump reliability. In my life I have only replaced or help replace 2 defective mechanical pumps. Both were on vehicles that were not mine. (A 1954 Ford and helping a GMCer at BS.) I also did replace the mechanical pump on my motorhome because it was free at the time to me. I was replacing just about every thing else on the engine after an engine fire.

Looking at electric pumps, I have had a reliability poor record. I have replaced 8 on vehicles that I own, 4 on other peoples vehicles. My daughter has an additional 3 she replaced and has it down to a 2.5 hour job including dropping and reinstalling the tank on her Blazer. I just remembered two more electric boost pumps that went out on the GMC. I carry a spare electric pump in my Blazer, Laurie's Jimmy, and my Colorado. Those are the only spares I carry other int hose vehicles than a serpentine belt and a few fuses. These numbers also do not include the fuel regulators (usually located inside the intake plenum) that at I have replaced that are part of the electric fuel pump system.

Let's see, that is 3 mechanical pumps in 30 years vs. 16 electric pumps in 24 years that I have been associated with replacing. Also throw in a 3 more regulators on the electric pump side.
