RACEPAK

hello.

my engine is obd2 with obd1 IM and Ecu....

on the obd2 manifold i used to have a RACV. with 2 water ports.

now i have a obd1 manifold with a obd1 iacv and now need to add a fitv cause my idle is crappy...

my q is is it ok to "T" one of the lines that goes to the iacv to the fitv?


thanks
