Working on an '88 f-150 with the 5.0 engine, had to do a head gasket (previous owner let it sit with just water, all freeze plugs were rotted out) when pulling apart noticed many of the vacuum lines were broken, and/or plugged. The emissions decal under the hood is gone. I have figured out most, but I have 3 ports with nothing, 2 on the ported vacuum switch at thermostat, and one on top of intake. There is one area where 2 hoses are electrical taped together, and lead to the canister, both come from the solenoids under coil. Any help is appreciated.

thanks

 

ok still have some issues, I have a line from the valve on top of the air pump that is broken (tan), and still have a port on the vacuum switch at the t-stat empty, I don't think the tan line went there, the line naturally wants to go towards the rear of the engine. Any other help is appreciated

 

ok got the tan line figured out (other end was inside a wiring harness) but still missing one port on the switch

 

This should help ...

 

my extension cord isn't quite long enough
