Wondering what kind of pump (how many cfm) you have it paired with. My company got the kit from LS and LS paired it with a 2.8cfm welch crv4 which I’ve learned may not be sufficient.
I think the crvpro4 should be sufficient for your 2L. If not you can always upgrade to a crvpro 6 or 8 and sell the old 4? Might be interested in scooping it up if you do end up upgrading! But like I said I believe the 4 should be fine… lS is pretty good about sending appropriate equipment
