1976 22-2 Fuel Line Routing

[StuZ654]

Hi all. New owner of a 1976 22-2 Center Console.  I am replacing the original fuel lines.  The supply line runs from the single fitting near the center of the tank forward to a hole on the starboard side of the deck, adjacent to the channel carrying the various electrical, fuel and steering components, then through the channel, and back to the stern.  The hose comes through the deck hole and through a wooden block that has a shut off valve. The wooden block is screwed to the floor under the console next to the deck plate that's removed for fuel tank access.  (Sorry no pictures)

My question(s) are:
Is this standard?  Seems the right angle the hose takes through the deck/block puts strain on the hose.  
In searching this site, I see supply lines running directly to the stern across the tank and under the deck.  Where do those lines exit the bilge?
Can I eliminate the shut off valve?

And finally, it makes sense to install dual batteries under the seat which flips forward.  Any comments on weight distribution issues?  I will be using #1 marine battery wire for a two battery switched set up.

Thanks for any answers and for a HUGELY helpful website.

Welcome aboard Stu  :!:  :!:
My tank is above the sole in my 170 so no help there.  My tank is below the sole in my 230 but I haven't had the need to dig into it yet - knocking on this wood desk in India.
Someone will pipe in here soon to help you.

Stu,  I am rebuilding a '75 22-2.  The fuel line route before the rebuild was forward to the channel cutout in the stringer then through the channel to the transom.  It immerged with the controls and wire harness through a rubber boot.  The fuel cut off was under the sole at the fuel pickup access port.  The wooden block you described does not sound original.  And, any 90 deg. bend in the rubber hose is a bad idea.

My rebuild will have a cut off valve in front of a fuel filter/separater (mounted on the transom) then run to the engine.  I put in a special chase tube to make sure the hose bends smoothly and is completely isolated from the bilge.

Check out the chase tube in my photobucket album.  Hope this helps.

Thanx MD.  Your pictures were definitely helpful.  I've run the fuel line through the channel and eliminated the wooden block.  No more crazy bends in the line.

Another question: what do you (or anyone else) use to seal the deck plate to the rest of the deck.  I am inclined to use GE 50 silicone?

I would steer clear of Silicone, use something like 3M 4000UV or 101.  Silicone will not hold up well in a marine environment.

Ditto.  Or, 5200.

4000UV or even "Life Caulk" is better than silicone.

Even though you already got rid of it I am going to add that my '73 22-2 that I am slowly rebuilding had that wooden block under the console with the shut off valve. The valve was rusted open so I  replaced it with a two-hose connector, and I just took off the wood block because I didnt like the looks of it. It was screwed to the deck and a hole was drilled through the wood diagonally into the deck below and the fuel line went through.

I just eliminated the wood so now the hose comes right up through the deck at a 45 degree angle under the console and goes right to the wiring channel back to the engine
