took my 03 F7 out for what was probably the last ride of the season this year over the weekend.stopped for lunch and gas and as soon as we took off i noticed a pretty good leak of gas coming from under the gas guage.i assume this is due to the gasket drying out and shrinking or cracking? is this a serviceable part? or do they make you buy a whole new guage? anybody got a part #? thanks!
