Alright...looks like not many people have tried this repair. Well it is DONE!!
I can change the gas filter in 3 mins and do not need special tools. I now have the same fuel filter on all 3 GM cars I own. Purolator F54714 or Fram G7315

I went to Lowes and purchased a heat gun. Very slowly I heated both the plastic gas line and metal barb. Used the low setting and heated them both for about 2 minutes ( first time, I used HIGH setting and melted the plastic line.

Maybe the hot water would have worked also.

A second person would have been helpful also. The key is... do not get in a hurry and slowly apply heat to the line and barb together.

Finally I put on two hose clamps and check for leaks...NONE ....
