Mice ate through 5 vacuum lines. 2 green, 2 red and a black. (See pic) There is also a sender wire with a burnt end that I don't know where it terminates. (See pic) The pic of the vacuum lines was taken from the cab and these lines are in front of and to the right of the carburetor and apparently routed to the rear of the engine on the passenger side. Full disclosure: a mechanic disabled smog pump and capped off the recalculating tubes off both sides of manifold. So these vacuum lines may have been " shorted". A diagram showing the colors or advice as to how to route them would be a great help. Also that sender wire. Many thanks!

Hello,

In the diagrams down below I have included all of the vacuum lines for the engine, cruise control, and the Heating Ventilation and Air Conditioning [HVAC] systems for your vehicle. The sending wire is probably going to be for oil pressure sending unit. I hope that this helps and please get back to us with how everything turns out.

Thanks,
Alex

Hi Alex, and thank-you for the quick reply. My engine however is the 460 ci 4 bbl, not the 302. It's in a Coachman cutaway RV. Does this help to better isolate the vacuum lines/colors? The 2-red, and the single black appear to have vacuum, the 2-greens do not. Let me know if you're able to provide further assistance. Many thanks Alex!
