Last year I added a T fitting to the 2 vacuum lines that run from the carbs to the fuel switch, et. al. and capped off the open ports which were to attach to my synch guage when needed with rubber vacuum capoffs from AutoAdvance. A few months latter, hard starting got me checking things and found these caps had split..replaced them and same thing happened once more. Apparently there is enough gas fumes in these lines to deteriorate the Buna rubber. Made a set of cap offs from 1/8" ID fuel rubber line lengths and blocked the ends with RTV/plastic plugs and should prevent this from reoccurring.
