Midshaft Through Hull Tube

I am replacing this and other through hull stuff on my FX-1 build and this tube seems to be an odd size that I am having trouble finding. I did a 144 tunnel swap and it sits 2” further back from where the stock 120 pump sat. That being said, the midshaft through hull tube is too short to reach the new tunnel. A 1 1/4 PVC tube is too large ID and doesn’t fit the bulkhead snug. Does anyone know where I can get a new tube??

Yeah OD wouldn't matter as much I should be able to make that work. When I was at the hardware store, PVC looked too big like the fit around the bulkhead would be sloppy and need to be filled with 5200 or something. I held this tube up to everything they had for pluming. I even called a plumbing specific business here locally and they didn't have anything like it. Maybe I was confused, I will double check tomorrow.

That’s the ID of sch 80 1 1/4 pvc, 1.204. HD or Lowe’s doesn’t carry any, and a lot of the Mom and Pop plumbing supply houses near me don’t either. Google sch 80 pvc for your area. If you’re in a pinch let me know, I got 60-100 feet of it in my yard, no charge for a hunk of it, sucks that shipping is a pia and more than it’s worth. Looking at the pic, it appears there’s a machined step in the opening of that tube, does it slip fit onto the back of the bulkhead ?

Yes, it is slightly machined and fits nicely up against the bulkhead. I can also fix that if the new pipe fits too tightly. I didn't realize there were different types of PVC haha Im going to check 1 more place today and I will let you know! Thanks a bunch dudes!
