    04 R1150R been sitting. Fuel tank rusty. Fuel tank & fuel pump options?

    I just got a 04 R1150R with 34k. It has a remus exhaust, wind screen, sargent seat and OEM hard bags. The rest of the bike is stock and in good condition.
    It has been sitting for 3+ years in a carport. I took the tank & fuel pump off to drain the old gas.
    The tank & fuel pump assembly are pretty badly rusted. I guess the tanks have liners cause its just a bunch of dried up big pieces of paper mixed in with the old gas now.
    I know this place fixes rusted tanks.

    Any other options used tanks seem pretty expensive and getting a matching silver one seems pretty hard.
    The fuel pump assemblys sock, lines, and even the in tank lines need replaceing. Can you replace the in tank fuel lines?
    The fuel pump assemblys body is rusty but i should be able to clean it.
    How do I clean out the rest of the fuel system lines, injectors etc just blow some sea foam deep creep cleaner or something else threw it all?
    This bike has been sitting for three years plus so what else should i change out before trying to start it and ride it.
    I am a BMW newbie but own and have owned a lot of the big 5 bikes mainly dirt bikes with carbs.
    Where are the best places online to get new oem parts and used.
    Thanks for any help I can see this is going to get expensive real quick which is what I am trying to avoid.

    www.beemerboneyard.com has kit for everything you've mentioned about the fuel pump/filter/lines/etc. for very nice price. I just did the whole kit on my 04 GS for $160 shipped. Fairly easy swap once I got the 5 gal fuel out of the tank.

    As for tank, they are one of the best resources for used parts out there, too.

    I had a very similar experience with a K75 that had sat with gas in it for 4 years. You can try jump starting the pump off the bike, but I found mine never would run until I totally disassembled it, which is actually possible by bending the crimps on the one end. The gears get rusted up. I cleaned it, and then it ran fine, but I ended up getting a new pump anyway. Euro Moto Electrics was my source, but Beemer Boneyard is also good. I found it was not a tough job to replace it all, and I hadn't worked on an "in tank system" before. I was surprised that after changing all the items in the tank, the bike started right up, and ran well. The injectors, pressure lines, etc, didn't seem to be affected by the stale gas that was left standing in the bike's tank. Maybe there's not enough of it in the lines, etc, to cause damage. I think I had about $200 in all in the fuel parts, by the time I was done.

    Unfortunately, the sender unit for the fuel gauge was also about shot from sitting in the old gas. If that's the case for yours, it could get expensive. They are pricey, and for mine at least, very hard to find used. I only say that so you won't be shocked if it happens. Good luck.

    Thanks for responses.
    I assume I should do all fluids on the bike and plugs. Any good sources & recomendations for them.
    Any other problem areas with the 04 R1150 I should look at or replace?

    If the brake lines are original, replace them with non-OEM lines. Spiegler, among others, makes a nice set.

    It would be a very good idea to send the injectors out to a professional cleaning outfit. They have the know how and chemicals to get the varnish and contaminents out of them. There are mail in places that will even measure flow rates before and after cleaning as part of the service and they are not that expensive. It is important the injectors have equal flow rates in big twins.

    Definitely a very good idea. I agree on using the Spieglers, too. They are nice.

    I also found the oil level sight glass on the K75 was so clouded, I guess from the oil sitting against it all that time, that it was impossible to use. I think they are about $40, and not hard to replace. You really have to have one that's clear for oil changes, etc. Possibly yours still is. Lets hope so.

    Welcome to the Forum redlines,
    Sad to hear the linings shot in the tank...you seem to have a thought on dealing with that.
    As a preventive item, if there is still a cable tie near the steering head nameplate on the harness headed from under tank to upper controls...cut it loose! A common issue here is caused by the hinge effect and breaking wires going to the controls on the bars...seems it is the kill switch more often. Either too tight on original install or just a bad spot to tie it down.
    Replace the quick connects on the fuel lines with a metal style, the OEM from that era WILL break at some point, sometimes a leak or spray while riding! All rubber lines in,outside of tank need replacing as mentioned, brake lines as well.



    A lot of technical stuff was put together on this site belowand is a great resource

    Good deal, thanks for the heads up.
