Hi evryone my name is Pieter and I am new to this forum. I have been logging on for the past few months and like what I see. I own a Kitfox IV with a 582 that I built it in 1992. The last 3 years it has been parked. It's now time to back in the air but I need to do some work. Originally built it with 2 13.5 gal wing tanks and the 9gal front tank. I never did like the front plastic tank because it smells and was tough to keep from leaking at the fittings. I am now looking at replacing it with a 4 or 5 gal aluminum version that I am building. My question to everyone is, why not put it up front. Everything I have read says put it behind the seat. With the original 9 gal tank I had no fuel starvation issues. Your comments would be appreciated.
