Hi people! I'm in the middle of a F20C conversion into my AE86.
Here's a pic if you want



However I have a couple questions...

Since I'm using the original AE tank, can I just T-joint the fuel purge tube into the return hose that goes from the fuel pressure regualator and to the tank?
I have no purge tank / system.



I also have 2 vacuum hoses on the front of the engine that are just cut, and I have no idea what they are supposed to go to.
What are they for and can I just loop them?



Any help appreciated

 

Yes and yes.

 

it still runs if you delete them....just follow the lines and remove all the ones that dont connnect to anything

 

The two vacuum hoses go to the secondary air injection system. Purely emissions related. Are yoy going to use a f20 ecu? If so you'll have check engine light. Won't effect performance though. Check into izzy's delete kit if it bothers you.

 

Ok thanks for the answers.

I have another question about the conversion.

I have a JDM engine with JDM ECU, does the fuel pump pin from the ECU give 12v, 5v or does is ground the circuit?
