350 holding tank

I have looked through the posts here and do not see one with more info other than to get tank from Duraweld. I’m looking for more info on replacing the tank what all will I have to take up and cut to get new tank in?

I posted a detailed plan with pics during the removal of the holding tank from our IP 380-88. Should be in the archives. Chess Harris, The Belle of Virginia

Hey, thanks for your reply I really appreciate it found your post that job you did looks great!
The tank on the 350 is not in the same place the little access door is forward and the tank looks to be under the forward birth door jamb towards the back.

Have to love it! For us, looking at that beautiful sole, and then making four blind cuts based on IP-provided scale drawings, was high anxiety, but proved to be spot-on. Yes, measured 3-4, maybe 5 times before the oscillating saw blade plunged into the sole. And of course, add the great ventalation down there, with the wonderful smells from the holed holding tank...a wonderful time.

I spoke with the folks in FL that made the original alum holding tank, and they gave a great price for a replacement. The Duraweld one was super nice too, all poly with a removable access lid for potential cleaning if needed.

Rethreading the access pipes into the installed tank was another high anxiety event too.

Good luck!
