Vacuum lines
Can someone please post a picture of a stock 73 L-48 motor so I can see the vacuum line routing. I have one hard line coming out of carburator not hooked up. Also I have a T with one line missing.I can't figure out how to upload pictures to show u what I'm talking about. Thanks

I'm starting to wish I owned an earlier car. There's like NO vacuum lines on there. Wow.
My 78 is bad and the 80 is a NIGHTMARE. I really gotta sit down and write a schematic for that one.

I've got to redo the hoses in my '81 and I think I'll start with around 30 feet of three different diameter hoses. I'll probably need more.

I will have a look at mine in the morning and take a picture of it. I have just removed the smog pump so there is a hose connecting both sides of the exhaust manifolds together where the smog stuff used to be but other than that it's all stock.

AIR tubes are plumbed into the manifolds. Best to either:
A) replace the manifolds with something better. Headers will pick up power. No doubt. Or go with the 2.5" rams horns, they do not have AIR fittings.
B) Buy threaded pipe ends. You can remove the AIR valves where the hoses attach to and thread caps on both sides. That'll make it look cleaner for now.

This might not matter to you now but maybe someday or some future owner would care. Just a thought.

Buy 1000 feet and sell your own vacuum line kit.
