1984 MERCEDES-BENZ 300 TURBO DIESEL, 1978 CHEVROLET K20 CUSTOM DELUXE
So ever since i bought my car a month ago i have been having to lock the doors right after i shut the car off or the vacuum would leak. After i looked into it i replaced one loose rubber connector for the vacuum line that goes through the firewall and now i can unlock my car the next day without worry. It holds 100% vacuum. Yay.
