Hi guys, I have a bit of a problem.
I bought a 'new' used tank, and installed it today. Hooked everything up.
This tank has two lines, plus the fuel line. One line is a tank VENT, the other is the overflow line. So basically they both do vent.
They route down the left side of the 2000 R6
So anyways, back to the problem.
Tank filled fine until just over half full. Then fuel just pisses out the overflow line. I called my boss (mechanic) who said the metal tunnel inside for the overflow is ruptured, and to plug off the overflow line.
I am a wee bit concerned about this. Mainly, that if it fails and it is plugged way up at the tank, that fuel will very quickly dump onto the hot engine below.
Also I was told to use gas-safe sealant and a bolt, into the tube on the tank itself. Is there a better way to do this?
Could it simply be that one of the lines is kinked and thus causing a vacuum, and the fuel to pull out? But even with the cap open and whilst filling? Is that even possible?
I have looked at all the schematics and service books. Not much about this prob.
See this diagram? A pickup hose goes from the tank to the pump, then pump to the fuel filter and to the carbs. I am thinking that the vent/overflow lines are indeed in the metal of the tank...there are no lines in any schematices that are secondary parts.
Thanks in advance.
