. I did an engine swap on a 2001 GTX RFI. Starts up great but then there is a long continuous beep and MAINT flashes. I am not sure if the beep would go off after time because it's extremely loud and I have neighbors. I found a hose under the area of the rave valves coming from the check valve tee from the rave solenoid (see attached photos) I can see it had a tie/clamp indent, so it must of connected somewhere but I cannot not find where it goes. Can you help me out where to look? The shop manual doesn't show the tee at the check valve it just shows a check valve hose going to the crank case. Most posts are for carbureted engines; being a RFI no carb. Any help with hose or beep is greatly appreciated!
