LS5 engine vacum pipe

[Tom R.]

Could someone post, or email me, a photo of the two metal vacuum lines that run along the right rocker cover on a 70 w/LS5? My issue is with the connection to the TSC and routing. I know the bottom one that comes straight off the TSC sits in the lower spot on the clip that's mounted to the intake manifold directly behind the choke. However, no matter how I rotate/route the one that comes from the top of the TSC, it does not line up with the top slot on the clip. That is assuming the bottom one connects to the rear of the carb (Q-jet) and the top one connects to the distributor vacuum advance. My photos before I disassembled does not have both of the metal lines attached to the clip and I've assumed it's because the rubber vacuum hoses have been changed/altered over the years.

Thanks

Buy your hoses, etc from the Doc as they'll be the ones you want anyway.

Re: LS5 engine vacuum pipe

That helps enough to indicate my upper pipe/tube has been bent/altered. Still, a photo would be great.
