Wouldn't that make it hard to fill up with gas?

I was noticing you could buy those under the deck Moeller tanks, they cost similar to the Aluminum. I was wondering what are the pros and cons of each. I reached out to RDS Aluminum and they said once I pull the tank to give them accurate measurements and pictures and they will give me a quote.

What are the measurements on the tank vs. the size of fiberglassed hold/“coffin box”? In other words, does the 40 gallon tank sit inside the hold of the optional 70 gallon? And someone was not able to snake all other cable/wiring through the riggging tube, as intended. Definately something to try and correct. Just my thoughts.

This is a pic with the forward fuel hatch secured, awaiting rear. Jus wondering how large your hold is in comparison.

Tom, this is the empty and cleaned up hold of my MA, 70 gallon.

so on my '77 all the rigging goes on the outside of the gas tank tub. I think you are going to want to do the same thing when you put it back together.

[TomParis]

I dont understand. In my case, the cables, and steering all go through a chase into the compartment on the opposite side from the baitwell and out to the motor. They come through the compartment that has the fuel tank and come up to the helm from there.

How else would you run them?

I do not understand how that tank could only be 5 years old. Looks like 30 to me.

tom: there should be some rigging tubes running outside the stringers. I'd definitely run them in the tube. Did you find the source of your leak? Check this article out for installing the tank, good info: http://www.marinesurvey.com/yacht/fueltank.htm. Good luck.
