03 limited v8 4wd. Swapped in bilstein 5100 with Tacoma coils up front and Fj coils in the rears with sso conversion kit. I removed xreas and all the lines. I removed airbags and the lines connections. There’s a question I have, there’s 3 lines from the “pump” 1 to each airbag and 1 to the left rear corner of the bumper. Looks like the compressor? I was going to remove it but it looks like it’s connected to something else? Evap/charcoal canister looking thing?
