If a vehicle requires the EVAP system to be tested for leaks, a modification must be made to the CH-52519 EVAP Service Port Access Tool.<\/p>\n<p>If the CH-52519 EVAP tool is not modified, or a commercially available low profile fuel line disconnect tool is not sourced to be used, it will result in the CH-52519 EVAP tool not being able to be removed from the EVAP purge line. The rib located on the CH-52519 EVAP tool needs to be modified in order for the tool to be removed from the purge line.<\/p>\n<p><strong>TIP:<\/strong> Performing this modification voids the tool warranty for CH-52519.<\/p>\n<p>To modify the CH-52519 EVAP tool, partially file down the rib (Fig. 17, #1) on the tool. File the rib evenly and do not file the rib flush as damage to the sealing surface may occur. Leave a small amount of rib material on the tool without damaging the sealing surface (Fig. 17, #2). This modification should not have any effect on how the tool works with other vehicles.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-14481\" src=\"https:\/\/gm-techlink.com\/wp-content\/uploads\/2021\/03\/F17-evap-3-R.png\" alt=\"\" width=\"740\" height=\"480\" srcset=\"https:\/\/gm-techlink.com\/wp-content\/uploads\/2021\/03\/F17-evap-3-R.png 740w, https:\/\/gm-techlink.com\/wp-content\/uploads\/2021\/03\/F17-evap-3-R-300x195.png 300w, https:\/\/gm-techlink.com\/wp-content\/uploads\/2021\/03\/F17-evap-3-R-85x55.png 85w, https:\/\/gm-techlink.com\/wp-content\/uploads\/2021\/03\/F17-evap-3-R-200x130.png 200w\" sizes=\"auto, (max-width: 740px) 100vw, 740px\" \/><strong>Fig. 17<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p>Use care to not damage, cut, or scratch the tool when filing the rib.
