Paul,

I would like to know if anyone has recommendations for a replacement for the oil injection lines. Yeah, I know about premix. IF I use Richard's "pump" I still
need lines to the oil injectors and I think it is crazy to pay Mazda dealers over $100 for the four lines when I can buy a whole car for a few more skins!
This is for a car but I may use in an airplane at a future date. Anybody found a solution?

Those little tubes are a real problem. The stock nylon tubes get brittle after ten years
and fracture. I wish Mazda used small steel tubing instead of that cheap nylon
tubing. Apex seal oiling is critical. I'll bet there are a lot of prematurely worn out 
engines because people did not notice the lines cracking and leaking.

I am not sure how you would replace those nylon tubes. Perhaps AN-2 hose if you can find
it. You would probably need a special tool to swage metal collars over the tubing
joints. Perhaps brazed steel brake line tubing.
