I'm getting ready to acid clean the tank on my 250SX project...so I removed the petcock assembly and inside the tank was a plastic tube with screens on it...well it wouldn't come out too easy and when I finally got it out it was pretty much fubar....is this piece actually nesessary? I was thinking....can an just run an in line filter rather than pony up the $20 plus dollars for this 5 cent piece of plastic??
