zhangwarship@gmail.com Posted August 18, 2015 Share Posted August 18, 2015 (edited) Hello everyone! Been a member from the first day I purchased my 1989 Seabreeze (National and Toyota) in 2014. First time to post but enjoyed a lot reading the posts. I recently moved to Portland OR and I am looking forward to meeting some owners in parks. I had some miss fire problem after purchase. It turned out to be the blocked fuel injectors due to long term (2+ year) storage of the RV (rust in the fuel tank) and failed fuel filter. Luckly, my mechanics fixed them and it has gained a few thousand miles without any problem. During the trip with miss fire issue, the hot muffler pipe (the holding clamp was broken) became in contact with the black water tank and burned large holes (~10 in long and 1 inch wide) as shown in the pictures. Based on my limited research, the tank is probably made of polyethylene and my two options are 1) plastic welding or 2) tank replacement. I have not asked quote yet. Could anyone provide some suggestions which way I should go? I looked at tank a few times when getting to underneath the motorhome. I am not confident that I can DIY. If I buy a replacement tank, where can I find one? Thanks for reading. Edited August 18, 2015 by zhangwarship@gmail.com Quote Link to comment Share on other sites More sharing options...
linda s Posted August 18, 2015 Share Posted August 18, 2015 Might be best to pull the tank to get exact measurements before you order http://www.tank-depot.com/product.aspx?id=163 Linda S Quote Link to comment Share on other sites More sharing options...
5Toyota Posted August 18, 2015 Share Posted August 18, 2015 my 87 dolphin national has an 18 gallon black tank . I would pull the tank for size . should not be too hard remove tolit the black pipes if ABS can be cut and put back with glue couplers. mine has one big outlet and the tolit flange.
