Eventually you’ll be able to just order the fuel line for the 2019+ Intake horn and use it with the 4th Gen horn. Otherwise, and for now you’ll have to have the line made. At least this is what a local shop has informed me of.I purchased the 4" Banks intake horn for my 19' after a member on here with a 20' said it would fit and shouldn't be any different then the 18'. I'm overseas so wouldn't be able to verify. Good to know about the fuel line not fitting. I e-mailed Banks awhile back and they said the 2019+ will be out soon. Here is what Banks is going to sell which is emissions compliant. I doubt they will offer any "off road" models but I could be wrong. I'm going to look for that new fuel line as well when it comes out.
