I too had fuel in the bielge mine was coming from pin hole around the fill hose connection and at the seams of the tank.

looks good and clean....I think mine is gonna be one of those stories that the tank is wider than the hole. I'm geared up for the extraction but i'm nervous about the reinstall. I've researched many post on reinstall but I'm trying to understand the wires that go to the tank. Did you pull new fill/vent/engine hoses while you were in there, they look new.

The reinstall is easy. You've got a pos and neg for the sender and a ground. If you get your tank custom made have them build it to the dieminsions of the hole in has to go through. I 5200ed pressure treated 2x4s to the bottom of the hull and then 5200ed the tank on top of them. Used a few tubes.

Correction on the sender (unless I don't know about the newer tanks), positive wire will go directly to the gauge (terminal "I") , negetive wire will go to the gauge (terminal "G"), tank and/or sender ground, then the sender wire goes to the gauge (terminal "S").
I have 2 saddle tanks. This was the post in the thread. Yours will be easier


Re: Specs
Got most of the electronics wired but figured I***8217;d show you the gas gauge set up with two tanks and one gauge.
Needed one pull switch that had basically an off, on, on (left & right tanks).

A regular 3 terminal navigation switch won***8217;t work. This 4 terminal did fine.
Don***8217;t depend on the schematic being correct, in my case the bow lights and battery were reversed.

The gauge had terminals for ***8220;S***8221; sending unit, ***8220;G***8221; ground and ***8220;I***8221; ignition or hot and a wire to the dash light bulb.

The ***8220;I***8221; terminal is fed from the hot feeding the navigation lights switch.
The ***8220;G***8221; terminal goes to the fuse panel ground and the two sending units frame ground.
The ***8220;S***8221; terminal goes to the three position switch to the common or in this case labeled ***8220;battery***8221;.
The other two terminals on the switch go to the sending units in this case ***8220;running lights***8221; for the left tank and ***8220;anchor lights***8220; for the right tank.
The remaining terminal ***8220;bow lights***8221; is vacant.
I connected the gauge bulb to the dash light switch but I didn***8217;t connect the navigation lights in the traditional sense by the first position being anchor and the second position being all. What I did was the first position would be all exterior navigation lights and the second position would include the dash lights. This way if the dash lights caused night blindness I could simply exclude them at night. I have a bad habit running at night without lights on so as to be able to see the water.

2x4's should run bow to stearn or port to starboard? Is that all it takes to secure the tank so you can hook it up and seal the deck back?

port to starboard with a gap in the middle to allow water to drain through the bildge. I think I used 5 or 6 per side.

Fwb , Yes all my hoses were new last season , and wires will be addressed before new install
