Tips on Kerosene tank location, pressurizing & fuel lines

[WesterlyPageant]

I'd like to get some input on tank location and plumbing for kerosene on board a sailboat.
I'm not interested in converting to propane, nor diesel. I searched long and hard to find both the Shipmate 3 burner stove w/ oven, and bulkhead heater. Both are in bristol condition.
I have 2 pressure tanks, one for each unit, also in great condition. The stove was modified at some point, there is a schrader valve (bicycle pump valve) on the face of the stove, near the burner knobs. The PO must have used this to pressurize the remote tank.

My questions are, where are tanks typically mounted, or how far away from the burner can I mount them and still achieve good results? I was considering tank locations either under the galley sink, or maybe in the cockpit locker. the latter makes it more difficult to fill the tank, but saves room in the boat. Under the sink would be a shorter run, 3 feet to the stove, 15 to the heater. Add another 5 feet if mounting the the cockpit locker.

I'd like to consider running both the stove and heater off one tank, which I understand means more complex plumbing. On that note, are copper flared fittings prefered? The heater came with copper, the stove was set up with all rubber fuel line. I understand there needs to be flexible line connecting the the stove so the stove and adjust to the heel of the boat, but can one run high pressure rubber fuel line the whole way?

I've read about a set up where a air tank was pressurized to 70psi, then using a regulator set to 15psi, fed the kerosene tank. This allowed more time between pressure top ups.
Thoughts on that?

Any tips are much appreciated!

I have used flared copper lines in the past but flex could be used all the way and would probably be easiest to run. I think using both heater and stove off one tank would work well - all you need is a T which branches off to each. Shorter runs are better but a long run shouldn't be problematic.

Don't fill the tank more than about 2/3 full otherwise you will have to pump pressure in often.

The remote air tank idea is interesting but may be more complication than necessary.

Not sure how these units work but my sigmarine bulkhead heater requires no more than 3 psi, anything more will over whelm the float valve and result in fuel overflowing. Also consider putting in a barometric damper as the first piece of stove pipe for the bulk head mounted heater.

Thanks for the replies. I'll start with rubber lines, Tee fitting, and a shut off for each unit. I'll plan to mount the tank in the cockpit locker and see how that works out.

Re the pressure, I find different info. I seem to find 15psi often, but the tank for the heater says 30psi.
I've been pumping to 12-15 and seem to get good results.
