Looking at the S5 TII lower manifold,on the inside.
I see the ganged bleeds for injectors(rubber hose goes from one injector port to another then out to face the firewall.).Can I use that for my Fuel regulator?(aftermarket).
I would like to use the other nipple for Boost/vacuum for my Defi boost gauge.
Thanks Gents.STYX!~
By the way,has anyone ever used that HEX capped port for anything?..Like a Intake temp sensor location?.

 

hex capped port is the other end of the ACV passage


use the nipple you intend for the DEFI gauge and use it only for the FPR and the ECU map sensor
and place the gauge somewhere else , like top or bottom port on alt side of UIM behind TB

 

Use the stock FPR nipple.

 

..and that would be?
I have the S4 TII Manifold on the s5 keg,sort of by accident when I built the engine up.I am putting the S5 Lower manifold on,so I dunno Crapola about no stock s5!

 

the fpr should see vac from both rotors. a simple water test (fill the runners up with water with the lim out of the car) and you will see what port to use.

 

it's on the LIM in the middle. It's the nipple pointing at a 45 degree angle towards the firewall

 

Thanks Gentlemen.
I appreciate all the answers.Cheers.
