If you are looking for an alternative to the plastic tanks for a trunk tank setup on your 2016-2019 Cadillac V3 we have came up with an alternative. This tank comes complete with all the fittings needed to connect your existing Alky Pump including the Low Level Sensor. If you do not have a meth kit you can add that as well. This tank is for the Alky Pump only, other brand pumps will not work. The tank mounts using an existing stud in the trunk, you will also need to use a Rivnut for the other mounting tab.
