I know vacuum diagram threads come up all the time when NZConvertible's diagram is floating around just waiting to be searched for. I have a question concerning his diagram though.

Background on the car is that it is an 87 TII that has the emissions deleted, Megasquirt ECU, OMP deleted running premix, aftermarket turbo so no twin scroll, fuel rails in parallel with aftermarket FPR.

I was replacing my vacuum lines getting the car ready to get back on the road since installing the Megasquirt, and I used NZConvertible's S4 emissions delete picture to double check that all my lines were correct since the car had the UIM off for a long while.

On his picture it looks like his secondary injector air bleed line is going to his cold start assist? Mine has long been blocked off.



Would I be okay setting my lines up like this instead? Excuse the poor paint skills.



Basically can I hook my secondary injector bleed line to the LIM in place of the FPR line, then just tee my FPR in with my MAP sensor?

 

Bare with me as my car is still under snow,so If I am wrong I apologize in advance.I am sure I got my secondary air bleeds going to the aftermarket FPR.(aftermarket rails too,so no FPD or FPR on rails)
There is a nipple on the side of the manifold to go to the Map.
If you have no Stock turbo,then I am thinking that you have no stock BOV(Air bypass valve?) so that can be hooked from BOV to a nipple on the Throttle body.

 

I'm gonna need help with my vacuum hoses when I put my engine in.

My charcoal canister near the firewall is gone so is my air pump , I've got an aftermarket bov too.

I was thinking of running premix and blocking off the omp but I probably won't.

Was considering removing all emissions and emissions rack as well, but I want to do it the right way.

Last car my na had white stuff in the filler tube because I removed my pcv valve , I used a fuel filter to try fixing the problem but it never seemed to go away. Don't want that problem again.

I don't have aftermarket rails, but I did take the ends off (and FPR and FPD). It has AN fittings now running to the aeromotive FPR. I actually still need to weld the bung on for my BOV, which is why I don't have it in my little drawing, but I will need to route that somewhere as well.

 

Ya,your setup sounds like mine..parallel fuel rail setup to the FPR.
OH!,if you check out the Single turbo section,there is a thread ...Like : 10 months without a BOV.
It is a good read too.
EDIT: 8 months sorry!
