Guest Posted April 28, 2009 Posted April 28, 2009 Some little bast*rds bashed my Gilera Cougar 125 against a lamp post the other night and dented the left side of the fuel tank, But now there seems to be a leak coming from underneith the bike just under the saddle from a small black rubber nozzel. I've turned off the fuel switch and it's seemed to have stopped(the vandals oppened it all the way to reserve.) I was just wondering if anyone had any hints to what the underlying problem is. Quote
Pete Posted April 28, 2009 Posted April 28, 2009 Do you not mean that they opened it up to prime? Reserve wouldn't cause a leak per se. However, that said prime wouldn't either...It sounds like it could be a damaged petcock (if it leaks on reserve). What I'd do is lift the tank up to check all the connectors and see if any of them have been damaged/come loose. I had a similar problem with my bike when I'd had the tank off and could smell petrol and it was gathering on top of one of my carbs. Turned out I hadn't cable tied the fuel line down tight enough Quote
Guest Posted April 28, 2009 Posted April 28, 2009 check all the rubber hoses are seated correctly, could be ones loose, they might have been trying to nick the fuel.. Quote
Guest Posted April 29, 2009 Posted April 29, 2009 it leaks when it's ON and in Reserve but does'nt when the the switch is off. it's leaking from a small open ended rubber tube right at the back of the bike just before the back wheel.They where'nt trying to nick anything they just bashed it off the lamp post and dented the fueltank. could this bash have disconected the fuel lines at some point.

Guest Posted April 30, 2009 Posted April 30, 2009 I'll upload a picture in the morning. if the vacume seal is broken can it be patched and repaired or does this meen a new tank?The leak is particularly rapid. the dent is about the size of an apple.and about and inch or two deep. Quote
