I found changing the oil when too hot w/my topsider caused the larger hose (the one with the clamp) to collapse, so I changed a few things....
Made a solid Aluminum replacement for the hose connector end that fits into the Topsider (tm) tank. Taped the center with a 1/4 pipe thread and installed a ball valve. Attached a piece of 3/8 hose to that. At the other end, used a few fittings to convert the 3/8 hose to 1/4 hose. All hose (tubing) that I used was high temp clear tygon tubing, so I could see the oil flow. All the fittings and hose were bought a Home Depot. If anyone has access to a lathe and wants a dwg of of the insert, let me know. I'll see if I can dig it out. Since none of these hoses are collapsable, I can change the oil when the engine is hot, and flows freely.
