I broke the oil injection vacuum spider and plan on doing the autozone route on those...but I have a question about a couple other things I need. The oil injection lines broke when I removed them...where can I get replacements that dont cost an arm and a leg? When I pulled the lower intake off the little grey plastic fuel injector spacers...cant think what they are called...came out. Do I need those? Any input will be appreciated.

There is how to make them yourself for a grand total of 20-25 bucks.
As for the plastic thing, is it the part on the very end? If so those are called pintle caps. Either way, if its on the injector I'm almost certain that you need it.

 

Naw...not the pintle cap. They are grey...or mine is....mazdatrix has them as diffusers. Are they needed to run?

 

Oh, the things inside of the block/intake manifolds. I thought might were yellow, but who knows. Anyway, they are not strictly required to run but they do help atomize the fuel. They are also a bit rpicey, as I'm sure you found out.

 

Ya,there are kinda expensive for being little pieces of plastic. lol. How will the fuel not being atomized properly effect the way the car runs?
