I am doing a bareblock S4 N/A. I will only have 3ea vac lines. I have the pressure sensor connected to the pass side uim nipple. The oil injectors to the front standard location (uim front nipple) and the fpr to the bottom of the three located where the oil metering vac line goes (their are three vac fittings there). Will this be good? Thanks

 

Well the air feed for the oil metering is atmosphere, if you are using the original location for it, it should be good to go.

For the fpr, any reason you dont use the stock vacuum nipple location on the dynamic chamber? I would put it there just becuase thats where mazda put it.

 

Where is that fitting located?

 

In the first picture the Atmosphere feed is the top, largest of the three

In the Second picture, the fpr vacuum source is where I am pointing to on the back of the dynamic chamber

 

there is 4 vac lines right

 

Got it running good now.. I only have 3 vac lines..FPR, Oil metering, press sensor..
