anyone know the exact size of the oem vacuum hose line and/or a good source for a roll of it for my December 1977 production date FJ? I am going to replace and number all the hoses.......any suggestions on numbering them?
Most of the hose is 3mm and the larger vacuum lines if you have any or your 78 are probably 5mm. You can get rolls online, or any european car parts place. NAPA has rolls of the non-metric equivalent that also works fine. Toyota sells OEM vacuum line in sections, but not too cheap.
