I'm in the process of taking the plenum and tubes off the intake. Plenum is off but tubes are stuburn. I removed all the bolts including the two under the plenum but the tubes wont break lose from the intake. Any ideas on how to break them loose without damaging them?

 

have you taken off the inside bolts, there is one up front and one in the back underneth the fuel regulator

 

Yes I have had...they seemed to be stuck.

 

IF you have ALL the bolts out then tap runner flange gently with soft hammer.The gaskets bond to the parts locking everything in place without the bolts.

 

heres a few pics to make sure you got them all out, should be 10 including the plenum.
