The engine's not going to be very 'stock' at all - I've got an Edelbrock 1406 on top of the 2750 intake. I'm not going to be using the stock vacuum tree. I'll be using the stock Ram-Air air cleaner only for the Ram-Air functionality... not much else. Also, going to be running a Holley Black electric pump, so honestly, I feel the need for the return line really isn't there. I was thinking of putting a check valve on the end of the vent hose and hang it vertical (just like we do with differential vent tubes on the 4x4s).
If I really still need to get one, now is the time to let me know, since I'll still have the ability to install it next weekend if necessary. Otherwise, I think mine will effectively be a 'closed' system.
Any advice regarding that will be helpful. Thanks in advance!
