I was thinking about electric fuel pumps for carbed boats. They don't return the fuel like injected pumps do. So how do they work? Do they just keep pumping dead head against the already pressurized fuel? Is there a built in relay to turn them off when they reach full pressure?
If they just keep pumping against the full pressure, why don't they burn up fairly quick? Just trying to wrap my mind around how they actually work.
