Help: Vacuum line and oil hoses
 

Went to clean my bac, and found a vacuum line attached to nothing (Pic 1), could someone tell me where it goes?

Also noticed oil metering lines were melted off (Pic 2), any tips on where to get replacement hoses, braided steel would be nice. I have no idea how long they've been melted, premixing now.

Car is 1990 rx7 (S5 i think)

Thanks in advance, Nathan

Pic 1) That line went to the boost sensor on the right strut tower.
It tells the ECU if you're under load (for Aux ports) or just cruising (for closed loop)

Pic 2) I replaced the OMP lines on my previous NA with model airplane fuel line.
I left the origonal line stubs & slipped the new hose over them.

Well... in pic 1... according to the FSM, the nipple that comes off a 45* angle closest to the front hooks up to the pressure sensor, and the one in rear is capped off. Not that it matters which one though.

If you could though, since your injector air bleed sockets are plugged in... could you tell me where they go? I don't have a S5 rat's nest... an S4 instead. When I remove the rat's nest, Id like to know where the air bleed sockets go, as they SHOULD be plugged in correctly, mine are just capped off for now. The FSM is NO help, all i know is its somewhere before the TB plates.

I would get the MOP fixed ASAP though...

SureShot: Thanks for the help, I really appreciate it.

poor_red_neck: Thanks, and I'll try and get the info you asked for. I'm still kind of new to rotaries, but I'm learning.

I'm not sure if the MOP is bad, but I don't know how to check it either.

You are correct.
You may have to get creative.
Any nipple upstream of the throttle plates will work.
Use the largest size available, and seperate the oil bleeds from the fuel bleeds if you can.

You can ger oil metering lines from atkinsrotary.com for 18 bucks a peice i just replaced mine with my rebuild.
