G’day and Welcome along mate!
Please post some pics of your bike and tell us a bit about your bike history etc.
I’ve got a ‘99 and I’ve overhauled the fuel pump twice in the 11 years 80,000kms I’ve owned it.
I’ve never considered replacing the external pump unit as parts are still available for it.
I’ve replaced the filter twice and replaced the pump motor once.
If they’re looked after they go the distance, but it’s crucial to keep the external housing wrapped with the insulation foam they come with… it prevents cavitation caused by heat transference from being so close in proximity to the crankcase.
Fuel cavitation is difficult to diagnose when it causes running issues and loss of power etc, the symptoms can often be mistaken for other possible causes.
Show us your ride mate… we love pics here at the oRg!
