There is one more part that I have found to fail: The sealing surfaces of the little check valves. They too will suffer from the evil ethanol, allowing the pump to lose prime as well as reducing the effectiveness of the pump.

The first rebuilder I knew (or who admitted) to use in-line electric fuel pumps was Andre Gibeault. He had them on all his CMPs, and certainly on his halftracks. He's dead now, so I can't ask him how they worked, but he seemed convinced they were the solution to his view of the circumstances.
