Some homebuilts use two of them instead of an EDP and one of the electric pumps runs full time with the other as backup. | |

| Jul 14, 2020 at 1:51 | comment | added | John K | The EDFP in Lycomings is pretty much an automotive pump as you'd see on cars in olden tymes before in-tank electric pumps. It might get a couple of extra inspections as an aircraft part, but it's otherwise identical. I just installed a cooling shroud on my pump, since I run my O-290 on auto fuel. The pump is run by a little push rod that is driven by an eccentric cam in the accessory case, and the rod works the pump lever. | |
