Can someone tell me how to route the vacuum lines for the primary/sec injector bleed off, and fpr.
I have an 89t2 orginal A-spec that I just rebuilt/added haltec e6k to.
I have 4 uim/rear vents....top three(2 small,1 med tube) all get routed through TB and bottom tube just goes into the uim.
I am using top two (pre-tb) for bleeds.....this is right for stock car with mafs but I removed that with my haltec.
So is it just a big vac leak now?

And the fpr is hooked up to the angled vent by the sec. injector fuel rail and I removed and filled/blocked off part right above it that has a t shaped gasket.
Am I sorced right and sould I have removed that part(sorry didn't know what it is called).

Thanks

 

Case u are wondering, she runs like ***.
Don't know if it is the engine breaking in/bad , haltec just set up, my porting job, or my vacuum routing.
need to start somewhere.

 

Well, first the FPR only needs one vacuum line going to it just like it did before. I have my stock FPR hooked to one of the nipples after the TB (engine side). I am little confused with your questions so I will just make some general comments.

With the Haltech you can just cap all the vacuum nipples you do not need. All I have is one for the BOV and one for the FPR. Oh yah, also for the MAP.

My guess would be that your Haltech is set up poorly at the moment. It will take some time to get it right. Just play with the mappings until you are happy with it.

 

Big line in back of UIM goes to brake booster

on my aftermaket Wolf setup I have top line going to boost guage, second down goes to stock FPR on the secondary rail and third is capped ...

on a J-Spec engine the brake booster line comes off the Lower intake manifold with a banjo bolt and a vacuum line coming off it...


on front side of UIM they are all capped off but one doesnt have both boost and vacuum ... wont know till I look at it tomorrow, the rest are capped off for me, and 1 vacuum/boost line comes from there and goes to my BOV since its got an FMIC ...
