I have a 2000 Trans am. Using my ac one day and it started shooting through defrost vents and to my feet. Was told hvac line from back of intake needs to be replaced. problem is Gm no longer has the part. I can't find it anywhere. I tried to use a different line but the male on the back of the intake versus the male on the check valve are two different sizes. What are my options? or does someone know where i can get this line? It is January in Florida and its 90 degrees i want my ac back. Thanks

(i know Ls6 intakes have the same size as check valve but ls1s are different)

They sell diameter-step adaptor vacuum fittings (plastic,
double-barb) at most auto parts places. Pack of those,
and a couple of bits of intermediate sized vac hose if
you aren't so lucky as to find a dia#1:dia#2 single step ?
