Day Tanks (Fuel) are IN!

Got the day tanks installed this past weekend. This did not involve simply putting in the tanks. It also included the following:
  • the glasswork for the port side main salon framing. Previously they were simply fitted and glued in. They got the final glass work: 2 layers, both sides.
  • permanently glue and glass the primary bulkhead between the engine room and main salon. I had previously cut and fitted this and simply left it in place anticipating I might have to remove it to get anything "big" in through the cockpit floor for the aft cabin frame-in. Well, the aft cabin frame-in has started and the biggest pieces are already in (and they came in through the companionway). So, I dont need to worry about this bulkhead to move stuff in. Therefore, in it goes, permanently. Glass tabbing, 4 layers, both sides.
  • Cut, fit and install a sideboard piece for the dinette riser. Which also forms one wall for the tank space.
  • Install (glue and screw) tank support cleats for a snug fit and paint the tank space with Bilgekote.
Before installed, the 21 and 17 gallon aluminum tanks were protected with a high build two part epoxy primer. The prep and paint included sanding the tanks with 80 grit (using a D/A), applying Pettit Metal Prep 6455, followed by two coats of Pettit Protect 4700 epoxy primer. Elbow plumbing fittings were then installed and tanks mounted using thru-bolts to secure them to the framing. Theoretically, I should not need access the tanks again until final plumbing for fuel is done.

Howdy

So, I see two fuel fittings (feed and return, presumably), and two other "small" fittings (tank vent…and what?). Where's the fuel fill fitting?
Or are you planning on filling these from the fitting using a pump from the main tank, with the main fuel fill on the main tank only?

Hey mickey,

The small 1" npt ports are for:

1- fuel feed (to engine et.al.)
2- fuel return (from engine et.al.)
3- vent
4- fill (pumped from the mains, not the deckfill)

Exactly how these will all be connected together (i.e. manifolds, pumps, valves, filters) has not been completed designed until we know exactly what needs to run off the fuel. In fact not all ports may be used. But they are there if needed.

-cheers

Grand! that was my guess! Do you plan on filtering/polishing between your main and the day tanks? Within your main tank? If so, any thoughts on polishers yet?

I'm waiting to see your switching/manifold system.

Yeah, polishing is a planned feature. Also, I hope to plumb things such any one of the tanks can be isolated in the case of contamination.

Check out the "Filter Boss" from kti systems. A device designed to allow polishing and multiple filters. Comes in a couple of variants, but they have their own special manifold system. I was figuring installing something like this.

I really enjoy your site. My wife and I are looking for a project boat. I think I will check the Westsail out. There are several for sale around the great lakes.
