Jake_Womack Posted October 5, 2015 Share Posted October 5, 2015 I'm needing to find out how the black and grey water tanks are attached to my 1989 Dolphin. I'm going to be welding a hitch on to the frame and need the tanks lowered for a proper weld. Does anybody know, or have pictures, of how these tanks are connected? Will there be multiple inlets on the grey water tank? Are the connections pressure fit, glued, clamped, etc... Thanks. -Jake Quote Link to comment Share on other sites More sharing options...
jdfrost64 Posted October 5, 2015 Share Posted October 5, 2015 some are glued with the older grey and black tanks and the newer tanks are just a pass threw rubber grommet that are either held up by banding strap or bolted or screwed by the edges. black tank will have a vent and main pipe. grey might only have one main hole but some tanks still use two a vent and a main Quote Link to comment Share on other sites More sharing options...
