Redoing fuel supply system

[R8rPhan]

Are there any diagrams that show how all the factory fuel lines are routed on the dual tank system (79 chevy C10 long bed)?

I have a fuel leak in the main line up on top of the tank.. Rather than just dropping the tank and fixing it the screwed up hack job way it is now, I want to get a new selector valve, install it (don't know where it's supposed to go), install the other tank, replace senders/pickups if necessary, install all new rubber fuel line, blow out/clean the hard line, and make it all 'right' as it should be...

But I need to know what 'should be' looks like...

Thanks
Mark

Ha! Where did you find that? I couldn't find the 77-80 range of docs..
I'll check it out... Probably answer a lot of questions...

I got them all from 73-87, download them from that site, all factory service manuals..

Unfortunately, it doesn't cover dual tank setups, or routing of lines along chassis...

But definitely some handy info in there...

Still looking...
