Not sure, but wasn't there some kind of recall or something with 07-08 regarding fuel pump losing pressure. I remember having mine changed out at no charge. Maybe the MOCO will foot the bill? Worth checking into.
There was a recall on the 2008 models for the fuel filter:
--------------------------------------
Safety Recall Campaign 0135
Harley-Davidson Motor Company, Inc. has decided that a defect relating to motor vehicle safety may exist on certain 2008 model year FLHP, FLHPE, FLHR, FLHRC, FLHRSE4, FLHT, FLHTC, FLHTCU, FLHTCUSE3, FLHTP, FLHX, FLTR model motorcycles
built May 6, 2007 through December 11, 2007. These 2008 model motorcycles may experience a cracking of the fuel filter shell leading to a loss of fuel pressure. This loss of fuel pressure can cause diminished performance and in some cases may cause an engine stall, or a no-start condition. This condition could lead to a crash which could cause injury or death to the rider.
