Perhaps "tap" is a confusing term; it can also be described as a "port". Either way, the hard black plastic line that runs from the vacuum pump to the brake booster typically has one or more "ports" from which various systems draw vacuum; the location and number of these ports are model specific and fixed.

The vacuum filter is installed downline from a vacuum port; if you are replacing an existing unit, then locate the original (left side of the engine compartment, in the vicinity of the oil filter housing), disconnect its two vacuum hoses and renew.

If you are retrofitting, then typically you need to cut open and remove a portion of the hard-walled white plastic vacuum line that is connected to the port and install the filter, using two short segments of vacuum hose [sequence, e.g.: brake booster vac line port - vac hose - filter - vac hose - vac line - etc]. You decide which system(s)you wish to protect. The procedure is quite simple; ensure that all fittings are leakproof.

You didn't mention why you purchased a new filter; unless you're retrofitting, these units aren't normally replaced unless they become oil logged or are damaged (cracked housing, resulting in loss of vacuum). If the unit contains oil, then you need to service the engine-mounted vacuum pump immediately.
