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.

I think this tank is not original nor was it new. I think it was repaired and placed in this boat. This tank measurements are as follows

22 7/8 W
48 1/4 L
7 3/4 H

Does that sounds like the measurements of what would have been in a 1977 20 Seacraft MA?

Roughly 38 gallons.....

Not original !
Have RDS make you a new one and be done with it for the next 30+ years..

They built my 80 gallon tank 30 years ago and still looks new !!

they gave me a quote of $480. That is more than I can spend on the tank. So I guess I will be rednecking it for now.

That’s not too bad for 40 gallons. What was the thickness, and was it coal tar epoxied?

I didnt ask what the thickness would be, but that is for a 35 gallon tank and without coating

I know RDS is local to you but try Sunshine Tanks for giggles. But you really need to specify thickness you want.

I was in a similar situation not long ago with the tank on my 23' - the tank (a replacement) had been foamed in. During a couple hurricanes here we followed local island practice of putting the drain plugs in, so rainwater would accumulate in the bilge during the storm(s) and the weight of the rainwater would help keep the boat from flying away (the boat actually moved about three feet during Maria but didn't take off, guestimates are that we had about 150 mph winds!).

Anyway, as part of a repower project I decided to yank the tank for inspection, and found pitting where water had sat and "cooked" in between the tank and the foam. The local reputable fellow who builds tanks said he wasn't interested in trying a repair, for his safety and mine. I might have been able to find a "shadetree welder" to give it a shot, and I thought seriously about trying a repair with JB Tank Weld, but a friend's mother was terribly burned in a boat gas tank explosion some years back, and that has stuck with me.

Also all the hoses were brittle, so I planned to replace them, and I didn't want to go through all that and then risk a tank repair leaking in the near future, and have to then go through the yank it out process all over again. So in the end I decided to have a new, smaller tank built - I'm going from an old thirsty carbed two stroke to a four stroke, so I expect to get about double the mpg, and will rarely be doing more than 25 mile days.

In the end I think you have to do what makes the most sense for you and how you use your boat... good luck!
