I have one on my 420A julian. As far as price goes, it all depends on where you get everything from. Best thing for you to do is search. You are the only one that knows how much money you are willing to spend. I bought mine for $200 not including the fuel lines. By the way..tick tock tick tock tick tock...track day is a couple of weeks away. Hope you will be ready to run with me by then.
