Re: Fuel Filter
I debated the replacement as well, however having stalling issues - I could think of no reason not to while I had the tank off. Be very careful taking off the fuel lines where they connect!
I also decided to have the dealer change the fuel filter, and darn glad I did. Not to say I could not have done it, but I did not want a hose clamp failure for one, and did not want to risk any unnecessary leak.
What happened to me was, one of the small hoses to the tank had a crack and a small slice in it, probably from trying to get it off, by me or from a previous repair. Replacement cost for one 5" piece of preformed hose was $75.
I decided there had to be a less expensive piece of high pressure hose somewhere, there was none to be found.
I used what I had around the house, not HP, and put the bike together. Big mistake! Thankfully I posted the question, and changed it before it blew.
I then had to buy a 3' length of BMW hose and install that, with all but the lower fairing installed. Not easy by any means.
Had I known better, I would have had two lengths of the 3' hose installed by the dealer using the tiny crimped connectors to the tank ends. I just did not want to risk any leaks vs the $20 charge to change the filter. It was worth the piece of mind to me.
In the process of all this, my fuel gage no longer works properly. Still not sure what the answer to that is. I have since used Sea Foam fuel cleaner in every tank, hoping that some debris got stuck in the float tube and that it might dissolve whatever is in there.
If you have a 99/00 LT, you may also want to disconnect the air intake temp sensor, which may cause hesitation. I too had not heard of that until I was done putting the bike together. Too late now unless I want to take the bike apart.
More than a few QD fuel line failures mentioned, so I did without. They are also about $85. If you go with the longer lines, you can take the tank off and not need to disconnect the lines, or, you can cut off half an inch, and have plenty for future service to do what you need to.
