Yes. You can replace the plastic tube with (4) 45 degree copper elbows and small pieces of heater hose. I did one of mine years ago. You can get the elbows at any hardware store. There are cheap, like $.50 each. Take the old tube with you to match the size. I think I used 1/2 inch or 5/8 on mine. You will also need a short piece of straight pipe on each side. As I recall the two sides are different diameters. This repair will save you about $80 Good Luck.
