Need fuel line diagram for dual tanks

[nuknuk]

1987 R10 Silverado 350 V8 with dual tanks.

I am looking for a fuel line diagram that shows from the sending units in the tanks to the selector valve for a dual tank set up on an 1987 R10.

Thank you.

This diagram of the fuel lines seems not to exist.  So if I can I will make one, once I figure it out.

I understand that a fuel line diagram would be convenient, but what exactly do you need to know?  Are you converting to dual tanks and want to mimic the OE configuration?

3/8" Feed line, 5/16" return line, and 1/4" vapor recovery line from LH tank run across the crossmember at the to the RH rail.  This is done via hardlines.  They go into the switching valve that is mounted inside the RH rail.  The RH fuel tank just feeds directly into the switching valve with rubber fuel lines.  The 1/4" vapor line goes into a tee under the switching valve and passes off to a hardline in the RH rail.  One set of 3/8" and 5/16" lines go down the RH rail to the engine.
