BMW R1200R R1150R/T F800 K1200R R1100R/T R1250R RnineT Message Board

OK, I'm stupid, I am installing new fuel line disconnects and I forgot to mark which is which and I assume it makes a difference. I was so involved in just getting the dam things off. I'm replacing the plastic disconnects with metal ones. looked through my service manual and couldn't find anything. I'd rather not have to take them off once I get them on.

On the tank, the 2 lines coming from the fuel pump plate - one of the fuel lines is coming from a point near the center of the plate and the other is out further. On the bike, the 2 fuel lines are going into a housing with one over the other. Which goes with which?

Any help will be greatly appreciated. I have a 2005 R1150R Rockster.

I'm not sure if this will help but here's the fuel tank blow up from the R1150R service c.d. It sounds like you're talking about item number 4 in the below image? Those appear to be the quick disconnects for the tank and in that case your male goes on top and female goes on bottom. You may want to get the advice of some of the other more experienced guys on here though. Good luck!

I've looked at the same page. What I can't determine is how the lines shown connect to the 2 lines( arranged one over the other)coming off the bike. Thanks for the try.

Rob

Ok I just went out and looked at my bike and then compared to #4 in the diagram (fuel pump plate). By "going into the bike" I assume you mean the section of fuel line behind the quick disconnects. The upper metal hose going into the bike has a male connector and the lower has a female (the one w/ the release button).

So, that being said, it looks like you need to connect the upper (aft) line with the line coming from the center of the fuel plate and the lower with the one coming off of the outer part of the plate (as long as we're both looking at #4 in the diagram).

That's the answer I was looking for. I'll give it a shot tomorrow. Worst can happen is that the bike doesn't run well and I have to struggle to switch them around again. But at least it's better then guessing. I should post pics. Can I do that here? Not sure how to do that.

BTW, sorry for not getting back sooner, went out for Chinese.

Thanks very much Beaze for the help and the effort.

Rob

No Prob Rob! Let me know if it runs good when you get everything together. Where did you order the stainless connectors at? I was toying around with just getting 'em out of the way before she takes a piss on my leg during a ride . Are they a pricey item (considering that they're stainless)?

I posted that picture by uploading it to Photobucket and linking it. You should be able to link via the "IMG"/"URL" buttons in the editing bar while posting or just copy the same code from your photo hosting site. If you haven't straightened it out by tomorrow I'll get some pictures of my bike posted for you so you can see how a working system is connected. Two tank pulls in one day is too much for me!

I don't know about any Stainless ones...but I got the chrome plated brass disconnects form Beemer Boneyard. The disconnects are identical to the stock plastic...except made of metal. The kit below inludes clamps that I thought were lousy. I bought better clamps at the local auto parts store when I bought the new fuel line (very recommended). Use fuel Injection hose and clamps only.

sweeeeeeet! I've got 1 more set of plastic ones left and then I'm swapping over to those! Thanks for the link.

I changed my battery this weekend "successfully" and the bike runs like crap. Sounds like it is missing. I checked the fuel lines and the fuel flow and all seems OK.

I will check the lines but pretty sure I put them back in order. The fuel lines went back as I marked them but the return lines were not marked?
Could that make a difference?

When I changed the battery in my truck it took some tome to recalibrate the computer, is this the case with my rockster or did I do something wrong?

Alex

Could be. Disconnecting the battery discharges the settings in the Motronic computer. They will recover over time as the computer "learns" the throttle settings. To reset the computer immediately, pull fuse number 5, reinsert it, switch the bike on, but do not start it, roll the throttle to full-on twice, then engage the "fast idle" lever, and start it up.

You might also check to insure the throttle cables did not become un-seated while taking the tank off and putting it back on.

Thanks JAS I will check the fuse first and then the throttle cable. My truck did the same thing so I will take it out for a ride and if it continues look at the throttle cable.

Definitely check that the toddle cables are seated. Same thing happened to me and I thought I had some bad gas ( ) or taking the tank off stirred up the fuel in the tank and the fuel filter was clogged. I was happy to find the cable unseated.

Rob

That is EXACTLY what I thought! That the filter was clogged or there was debris in the line. I will run it tomorrow and if it does not correct I will pull the tank off and check the Throttle line.

Thank you guys a million for the help....


Alex

You shouldn't have to remove the tank to see if the cable is seated correctly. Here is a picture of where I found the problem:


Since the cable is spring loaded, just center it and it will seat itself.

65 degrees in PA tomorrow; I going for a ride.

Rob H

I can not thank you guys enough. After looking around I notices that the most excellent diagram pointed me to the throttle cable that was slightly ajar.
I centered it and the bike runs better than ever

Again the photo with diagram and the effort put into posting it was EXTREMELY helpful and appreciated.

It solved my challenge and made for a great ride today in Houston.

Thanks again......
