I would it be ok for me to run only two oil injector with premix. one of my oil line crack and i was wondering would it be ok. I think it would be have you anyone ever done that before.

 

I'm not sure if only 2 lines could hold the output volume of the pump.

 

Replace the lines. Buy a new set from Mazda or Mazdatrix, or make your own using lawn lower fuel hose.

i look at that thread today before i post this up..i went around town trying to see if any store in here have teflon tubing and couldnt find a single store that have those.. im returnin my old motor tomorrow to the junk yard..i will see if they have any over there and if they dont..then im just going to make a block off plate and prmix....i would still pass emission with premix right without the omp.

 

Use lawn mower fuel line like I said. It's cheap, easy to get, and works fine.

You can get the materials for a grand total of something like 25 bucks. All of the parts are listed here: https://www.rx7club.com/showthread.php?t=348068. Just do that and don't mess with anything from a junkyard as its almost definitely not in good shape.
As for running on 2 oil injectors and premix, if you can run with no OMP and premix, then what makes you think running on 2 injectors and premix would hurt it? Just use 1 oz per gallon until its properly functioning.

 

Well that true but if i cant find anything tomorrow then im just going to create a block off plate and premix it. and maybe when summer comes around i might do the premix mod.
