Vacuum Line Shape and Routing, Pics Please!

I need a picture of how the correct vacuum line should be routed to the carb?  Shouldn't there be a loop above the valve cover/carb to prevent back flow of vapor so gas doesn't get into the distributor? I know many old cars have this shape.  My valve cover also has three clips on the right side, did the line travel along and around the cover through these clips or were they for factory wiring supports?  Mine line is all bent up and needs replacing when I install my new carb soon....also, how about the correct metal fuel line shape and location? Might as well replace that while I'm at it too!  Thanks.

Dunno if this was orig or not, but hears what mine looked like (2nd gen)...



The loops on the valve cover were for the orig oil pressure light, Distrib wires and engine temp light (at least on mine they were).

Cool, that's basically the rout mine takes now, around the front. Thanks for the quick reply. That's a nice clean engine...one thing, I would move that fuel filter to under the frame before the fuel pump and away from the engine for fire safety. Old VW owners do that too, never put a plastic filter near the manifold, they do split open and....I like the sliding support rod, I recall my '66 had that set up and not a chain like my '64 has now.

LOL...ya...that's an old pic after trying to just get by redoing the head. The engine has now been completely rebuilt, with an HEI dist, and I bent a whole new fuel line from the pump up to the carb (no filter). Now in process of finishing up brakes and a rewire kit.

is that copper fuel line? and is there a reason for that? is copper better than aluminum because of the ethanol/aluminum calcification? and where is that other EGR(?) tube going to? nice lookin' motor. Mine's almost the same but haven't got the "Chevrolet" valve cover on it yet. were those valve covers original to sec gens or just 1st gens? (sorry to pepper you with so many questions)

It was copper...probably because it was easier to bend...LOL. Now it's steel. The EGR was split between the intake manifold next to the carb (where it should go) and the vacuum control on the PowerGlide trnasmission that used to be in my van. Now, the EGR only goes to the intake, and the vacuum control on my TH350 transmission comes off the intake below the carb (in this old pic you can see some little square hot idle compensator sticking out under the carb by the seatbelt).

I have looked at this pic several times, still can't find an egr valve. Do you mean PVC valve?

Lmao, yes the other vacuum line off the pcv valve. Guess I just spaced out. ;-)

As soon as my Carter YF arrives, I intend to make a steel line over the valve cover as you suggest, I'll put a slight upward jog in the line from the carb to raise it as high as possible above the hot cover and then down to the pump, fun with a tubing bender 101! 5/16" ID or OD? as long as the ID is at 1/4" should be OK?
