I just re-ran all the vaccume lines and set the timing on my 83 toy (22r). And the vacume lines i used were a bit smaller than the ones i removed, I am wondering if the smaller line will colapse under pressure or if it will be ok. Any input is greatly appreciated...

as long as you replaced the vacuum lines with ones that are ment to be used as vacuum lines there shouldn't be a problem, otherwise, yeah they might collapse also if you have a vacuum gauge with the pump on it you could test them with that
