Plumbing, Fresh Transfer pump from Harbor Freight

[Teranodon]

As everyone knows, Harbor Freight stuff can be great or lousy, depending. Here's an inexpensive (under $10) battery-powered transfer pump that I've been using for about a year, and it still works. I've only used it for water, but it's supposed to be good for oil, diesel. It takes two D cells.

Now--how much water are you pumping? As in, what is capacity in gallons of my bow and main tanks....

I have this same pump - it's handy for all sorts of things. I've also used it to pump coolant into the overflow jug. I added a rope and carabiner to mine after losing my first one to the bottom of the lake.

I have a similar one with a strainer on the intake to drain the oil from my turkey fryer.

I have a similar one I have used for years to transfer fuel from jugs to the boat. Much easier and more controllable than pouring. I don't like all the time it takes to go to the fuel dock. Works great.

I'm not so sure I'd be comfortable pumping diesel fuel. The thing is very cheaply made, and electric motors can spark. I fill 5 gallon jugs at the gas station, then siphon the fuel with a siphon:

We have used the 'rattle syphon' for decades and it works well.
