I plastic welded the 110 gallon water tank in my trailer, paid someone and it lasted 1 year my job has been in there at least 5 years. Glue is a no go on the white water tank. I believe ABS glue is good on the black and I have herd of melting some abs in acetone and can spread it on the clean roughed up tank. Been awhile since I researched doing the repair on mine. you will be ok
