Vacuum connections 84-85 351 4 barrel carb
Hi From Sydney Australia. I have a 84-85 F160 XLT Lariat HO 351 with the Holley 4 barrel carb. I just had it overhauled, looking for vacuum hookup diagram.
Or failing that, where does the vacuum hose on the accelerator kick down vacuum diaphragm connect to - manifold or Carb? Only diagrams I have found on net are for the EFI models. Any help appreciated. Especially a complete vacuum diagram.

Thanks for that, unfortunately whoever had it before had the radiator replaced and all the decals were removed. Main interest is to know where the Vacuum Operated Throttle modulator hose connects. I think it may be to bottom of Carb. However any idea of a source for the full vacuum hose connections on the 351 4 barrel Holley 4801C would be appreciated. Everything I have come across is for the EFI , not the carb model , ( Build date for mine was Nov 84.

The vacuum diagram differs for each vehicle. Here's the one for my 1986 351w HO. It might be close to yours (since similar engine setup/years) but it might be slightly different than yours.

Kickdown goes to manifold vacuum.

Thanks for the help. DO you know where on the manifold the Kickdown decal vacuum attaches? Clearly the Carb model has different connections to the EFI . What hose should be attached to the vacuum outlet on lower left front of carburetor? Motor seemed to race once hot.
