Looks good. The slimmer console fits good with plenty of room to walk around. I was and still am thinkin of addn a coffin to the front of mine.
Yeah the clamps is what first caught my eye. Definatly two clamps if not three just because they are cheap. Maybe S&P could have made the fill barb alittle longer so people can mount two clamps. IDK.
Keep the pics comin.

I'm with Ken on the double clamps. It's not just a good idea, it's an ABYC standard; two half inch wide clamps on all large diameter fuel hose. Clamps should be 100% 316 Stainless.

There is not room for two clamps unless I buy those thin clamps. A beefy clamp like I like will clamp mostly on bare hose and not the barbed fitting? I do not think that is good? Maybe since you proved My urban legend wrong I will atleast double the fill and vent hose. There is plenty of room on Those. I am not doubting you? I just thought if I have not ever seen one fail it must be one of those urban legends? Like not putting a battery on a cold concrete floor? That was when batteries were made with glass?

Steve D'Antonio, who wrote "The Incredible Mr. Moesly" article in the literature section, used to manage the Zimmerman Marine boatyard in Va. and now a noted marine consultant, says: "In fact, there are no requirements of any sort governing hose clamp use in boat building and repair, at least not for recreational diesel-powered vessels. The American Boat and Yacht Council’s recommendations call for double clamps in only two locations, fuel fill hoses and exhaust systems (my own guidelines add stuffing boxes to this list). While double clamps are undeniably desirable, in any other location they are optional." He makes the point that double clamps can do more harm than good if you try to use them on a hose barb that isn't long enough to accommodate them!

Steve recently published a couple of EXCELLENT articles on hose clamps: http://www.passagemaker.com/subscrip...lection-part-i, and http://www.passagemaker.com/subscrip...lation-and-use If you click on the pictures at the bottom of the article, it will bring up comments illustrating the point made by each picture.

I personally prefer the solid band clamps with embossed threads made by AWAB because they're fairly narrow but very strong and don't have the perforations that cut into the hose. The local Boat Owners Warehouse store carries them; they're a little more expensive than the perforated band clamps but they're a very high quality clamp that won't damage the hoses. I like to use 1/4" drive sockets to tighten clamps in hard-to-access areas, and the only downside I've found is that the bolts on the AWAB clamps require metric size sockets, so you'll need some small 7 & 8 mm sockets in your tool box for that!
