Custom tank with aftermarket petcock >?

[riotten22]

Hey guys I have a Benjies fiberglass tank that came with new petcocks but these new petcocks do not have a port for the vacuum hose that attaches to the carbs like the stock tank / petcock had. Is this goinig to be a problem with my stock XS400 carbs? Does it need this vacuum line to draw fuel to the carbs?

No, just cap it off with a vacuum cap. it is there so that you don't have to turn the petcock "off" every time you stop somewhere. Just get used to flipping it to off and you'll be fine!
