    Default Spectra Fiberglass Tanks ?

    Does anyone know, how many gallons does the Spectra 20 stack type fiberglass tanks hold? The measurements for the tanks are: 7'.1" long 16" tall.


    Thank you & Happy New Year

    You do not want to reuse those glass tanks if you are using pump gas. The ethanol in our gas will dissolve the resin and cause you all kinds of problems.

    Is there anything that can be done to seal them from the fuel ? Because these tanks are still good and knew ones are crazy $$$ wise !

    You can use this calculator to get the actual capacity- http://www.greertank.com/tankcalc.htm

    A
    lso, check with a local radiator shop to see if they can coat the inside of the tanks. I had one done about 15 yrs ago but it was a 10 gal stationary tank for a home generator that as far as I know is still being used.

    Honestly wouldn't waste time with the old FG tanks , for the aggravation and saftey factors alone not to mention what it would take to try to make them work (cleaning and coating etc) this particular boat had no less than 10 gallons of varnishy fuel in the bilge and tank voids , new tanks like these we're installing were about 1K and made dead nuts to our measurements Tom





    ya don't want one of these for sure ....

    To figure out gallons. In inches, use L x W x H /231. it might tough to get accurate since the tanks are not perfectly square.

    ...For the width measure the tank from top to bottom on one side of the tank... ...Whatever the center of that dimension is should be fairley accurate for your calculations,...if both ends of the tank are the same...
