Re: another fuel lift pump question....
I have a spare electrical pump on board already. Perhaps its best simply to by-pass the engine lift pump and go directly from Racor filter to the engine mounter filter.
If the electrical lift pump failed, I could rig a temporary fuel supply with gravity feed to get me home in any case. Changing the electrical fuel pump in a lumpy sea would make me kinda seasick, methinks. It could be done fairly rapidly though. They are normally very reliable. The last one lasted 20 years.
In all the years I have owned the ship, the engine room electrical bus has never lost power so perhaps I am worrying too much.
