sounds like you have a burb tank, not a blazer tank...... most use blazer tanks, 20 gals+, some have used burb tanks, 30 gals+ & others have used custom tanks from a board memeber or a manufactered fuel cell..... check the FAQ and try "search", there is a ton of info & photos on here about different tanks, fuel piping/routing, fuel doors, locations and how to install.... good luck!
