Yes, it is a big job. But, not just the filter needs to be changed, at the age of your bike you need to change all the hoses in there and use proper clamps. The best clamps are the Oetiker crimp clamps that use a special tool to sqeeze tight. Look on the internet. The kits from Euromotoelectric have the hose and clamps with the filter if ordered. Call them for help as they are good. Lube the new gasket for the fuel pump assembly when going back together. A little bit of grease or oil. Send me your email and I'll send you the Service manual instructions on how to do this <[email protected]
>. The file is too big to send to this forum. It has illustrations for all the plumbing and such. beech
There are fuel injection rated screw clamps but they have to be very snug, and not as good as the one time use Oetiker units.
