Does anyone know of a fix for a crack in the black holding tank?

Another one for JB weld. I fixed an air ride leak on a new MH....it lasted for 10 years and was still working when I sold it and holding 125 PSI. Walmart or any auto parts or hardware store.

Whatever adhesive you use you shuld probably test it first on a small section of your tank to see how well it adheres to the material your tank is made of. You might also scuff up the surface around the bond to get a little better mechanical bond from the adhesive. One thing I have done is use multiple coats of the adhesive and put strips of fiber glass tape in it to strengthen the area. Did that around the outlet pipe where there was a strain area and it worked well.

Any of the adhesives mentioned and then I would put a piece of Eternabond over it.

X2 on the Eternabond. I fixed a shower pan with it. So far so good.

X2 on Plasti-Mend

not cheap, but cheaper than new tank

Depending on the material the tank is made of, a hot air gun and an appropriate filler rod would probably be the ultimate repair. Anything else, you take your chances.

If you can slice off a thin sliver of the material, you can find on the internet a plastics identification test (usually using a propane flame and observing the sample's behaviour) to narrow it down.

A lot of adhesives will not stick if made of polypropolene. The only way to repair is to find someone who can do a plastic polypropolene weld. We had to remove our tank and they were able to do a weld

MY tractor has a plastic fuel tank. I got a leak in it and went to the Automotive supply store to get a plastic fuel tank repair kit which is just a special epoxy made to repair plastic tanks. I do not remember the brand name but they sell those kinds of kits at most automotive stores. That was 4 years ago and it still does not leak. If it can seal a diesel tank that gets bounced around in fields and crossing ditches ruts what ever else I drive over. I think it will repair your black tank just fine.

If cracked drill a hole at each end to stop the crack.

1/8 is all you need.

Out of curiosity, how big is the crack length wise?

If it isn't to large you could pickup one of the expandable rubber plugs. Drill a hole the right size and drill out the crack. Easy greasy fix. If it is a couple of inches long.....not so much :-/
