Why don't OEMs merely offer the option of dual in-tank fuel pumps - operating in parallel with each other? The chances of both letting you down at the same time are infinitely less than one letting you down.
$$$$
Ford - for instance - offers all kinds of non-standard $$$$ options for it's E350/E450 series of vans used under various commercial service applications ... dual in-tank electric fuel pumps for ultra reliability could be one of them. If available for motorhomes, I'd pay for dual in-tank fuel pumps in a heartbeat whenever buying a new Class B/C motorhome built on one of Ford's van chassis.
P.S. #1: I would have paid extra $$$$ for a limited slip differential and dual alternators, too, if Winnebago/Ford had offered the combination when we bought our new E450 based Itasca motorhome.
P.S. #2: I would have paid extra $$$$ for the good old easy to access individual/separate engine equipment drive belts instead of a hard to get at and snake around pulleys single serpentine belt, too ... so that if a belt broke you would only be partially disabled instead of completely disabled like you are with a busted serpentine belt.
At issue is you have two pumps working at the same time wearing out at the same rate. Your second pump might not fail at the same exact time but it would be close. You'd be better off cost wise replacing the pump at a given mileage interval. Besides, it would cost s fortune for the manufacturers to make the option available for the very few that would opt for it.
And yes, I do remember the bad old days with all separate belts. It was a pain adjusting the tension on multiple belts. The one that broke was always the one on the inside requiring the removal of all belts. They'd last about 30k before you have to replace them. The newer serpentine belts will go 150k plus miles and require releasing the tension at one point. It took me less than 5 minutes to replace it on my SUV and that was from opening the hood to closing it. Bam, done for 150k or 5 years.
