1-Is standard fuel hose OK? I couldn't find high pressure, so I just got regular.



2-One of the injector aerator screens broke out of my UIM. Will this cause a problem?



3-I ran my FPR to the LIM vacuum nipples right in front, where there is a pair of them. Will this work, or should I move it to the back of the dynamic chamber?

I'm not looking at my car but I will try to help you



1 - From what I understand all the "standard" fuel hose you get in your local auto parts stores is ok for our cars... I've been using the same in my car for a few years with no problems.



2 - I don't think so. I have run with and without them. Just make sure the injector is still seated/sealed properly. That thing is supposed to provide better fuel atomization... like you or I would notice the difference on our s4 NA's



3 - I'd move it to the dynamic chamber nipple. There's a reason Mazda is using that one. You may get not enough or too much vacuum somewhere else.. I don't know.

Not sure what "standard" fuel hose is, but I would be sure to get hose specifically made for fuel injection, since the typical injection pressure is around 40+ psi, and carbureted systems run about 6 psi.
