Fuel Pump Leak!

Hi Guys,

I having some issue with my 1200 GS at my Fuel Pump.

Attach of photos for better understanding.

It was leaking very bad as I thought it was the O-Ring need to be change but I believe it was worse than I thought of.

From BMW, they say I need to change the whole pump system which will cost about $300 US, which I think it is too much and it is only just that fuel release need to change and it should be ok but they don't it by itself need to buy the whole set.

I was thinking if anyone here having the same issue as me and able to help me out.

Thank you all.

Regards,
Black

From what I understand the female part of the quick disconnect is molded into the plastic that makes up the fuel pump flange. There are two versions, one for bikes without the on board computer and another for bikes with the on board computer.

http://www.realoem.com/bmw/showparts...05&hg=16&fg=05

shows the details for my bike. Item number 4 is the part. Ignore the Price column on that page... it seems to have no relationship to what people actually pay.

If it is the male part of the quick disconnect that is leaking you can get one for about $25.

BE SURE YOU CHECK THE CONDITION OF THE O-RINGS! A bad O-ring can cause problems. I keep spare fuel line O-rings as part of my emergency kit as I'd hate to fix a problem on the road that required the tank to come off and then find I can't go anywhere because I broke a 50 cent O-ring trying to put the bike back together.

I am not clear as to what exactly your problem is...if it is
leaking threads it is common in auto and aviation to use a
product referred to as "fuel lube". I think it is a lubricant as
well as a sealant. Its been around for a long time and seems
to cure any and all fuel system leaking problems. It is good stuff.

Also, it looks like the thread have some residue of some sort of sealant
on them...maybe teflon tape which is a no-no in fuel systems. I would
wire brush them to get the threads cleaned up.

When I took out the quick disconnect, there was this white sealant around the thread which were damage that is why fuel keep leaking... Just need to replace it with O-ring and hope it will work and no leaking anymore...

It looks like you are on the right track. If possible check any
internal fuel filters to make sure they are not clogged and creating
high pressure pumping issues.

I do not know about fuel filters. Since fuel cleanliness is critical
on fuel injection I assumed there was some filtration some where.
