1973 196 rebuild question

[Duffy1470]

Rick, I’ve been thinking about the water pooling thing in the stern where my gutter trough is and am thinking some sort of slope like a portion of a pyramid only longer and flatter. I am going to cross that bridge when I put the deck down. Got my tank today looks great. $1800 though, ouch. There goes my budget. The guy who did it is in Elberta AL. I would be glad to share his info if anyone in the mobile Al to Pensacola Fl area is looking.

I hope you understood the drawing I made to show how to slope a portion of the deck on each side. a 1/4" side to trough slope is enough to drain the deck.
If you received plans/drawings for your tank you can post that and the builders info in this thread https://classicaquasport.com/smf/index.php?topic=11420.0

Got my tank. I did understand what you were talking about with the corner slope. Thank you for the Input,  very helpful

[RickK]

Ok, I'm confused about how your tank was made. What are we looking at in the pic of the tank? I see a sending unit and 2 other things - 1 I assume is a fill pipe and the other? Maybe the vent? or the pipe connection to the engine? Maybe what I think I am seeing as a fill pipe is actually the outbound pipe to the engine?
If we're looking at a fill tube, is the fill tube on the correct side? Usually the fill hose and vent tube are on the starboard side. Reason I ask is I see a lot of pictures lately that seem to be flipped 180 degrees vertically, which makes for example, people you know that are right-handed (watch on the left arm) now have it on the right. I am not sure if it is a camera thing or a mode that pics can be taken (like regular or selfie). So please enlighten me - is the pic flipped or are you running the plumbing from the port side?
Trust me I have not been drinking

Drinking or not, you are seeing it correctly.  It is the fill and the vent.  The fabricator zip tied some fabric over the openings to keep dirt dobbers and debris out of it so it looks a little weird. The guy built it based on pictures and measurements I sent him.  They are located where I wanted them but the angle of the fill is the wrong direction. I may be running them to the port side. It's just one more thing to do.
Laminated some tonight on port stringer.

Ok, so I wasn't seeing things. Going out the port side is not the end of the world. I have mine going out the port side.
Is your sending unit right there too? If so, do you know what kind of unit they installed? Is it an offset float or one that is directly below the unit? Also, where is the output to the motor? Out of our sight, on the other end of the tank?

[Duffy1470]

Sending unit is out of picture at stern of tank. Adding some storage under the leaning post seat. Used the corner of the old fuel tank. Will need to make a side but will do that this w÷kend. Laminated some more of Port stringer

[Duffy1470]

Not sending unit. pickup is out of sight at what will be the stern of tank

[Duffy1470]

To your other question, I do know what type of sending unit was installed.

[RickK]

Reason I asked it that with the sending unit in the bow end you won't get a good read on the amount of fuel, especially when cruising. I see you cut open the old tank, what kind of float did the original have?

[Duffy1470]

It had the toilet bowl type with the float on an arm. Finished the leaning post storage and glossing the "Coosa risers" on top of the stringers. Baseball bat solid.  I had one section of glass I was unhappy with but not enough to grind out. I found it is near impossible to grind glass off Coosa without damaging the coosa.

This tool is helpful for angels and it was cheap. Get one if you don't have one

Tank fits. Should I support it from the bottom? Currently it has a point of contact on each side mid tank and the back corners appear to touch the hull. I was thinking something like below in each corner or a tube down the center. I have some solid rubber mats I was going to incorporate.

[Duffy1470]

Tube or build piers out of Coosa blocks and rubber mats

[RickK]

I would use 3 tubes across to spread the weight across the width. They should be beefier that what you show, maybe 4 layers of 1708. One or two of the layers can be what you use to wrap and attach to the hull. If you are going to use short ones like shown, I would use 4 or 5 rows deep. The height of them will be different as you move forward and aft. You want a little angle toward the aft to keep the fuel to the aft.

[Duffy1470]

I talked to the fabricator of the tank and he recommended the tube method or the glassed in pier  at each corner of the tank method. I felt my skill set lent to the pier method. Here is my stab at the front piers.
