I swapped my eaton for a ported eaton, did fore fuel rails, 80lb injectors and all new braided line. In the passenger fender well theres a little canister that is for EVAP (i think?) from that canister there are two hoses that run through the hole in the fender well and into the bay, one went to the intake elbow the other has a cap on it, i think its for testing the system? Can the intake elbow one be capped off or can i delete the whole system since im going return style with a divisionx hat...
