tank removal for electrical tear down - help!

[cmejia1978]

So I bought this pristine harness many months ago and now it is time to use it since I have to much electrical sh$t on my bike that is giving me hard times, so my very first question: which would be the best approach to remove the fuel tank of my 2002 620ie? I have some gas in it, so do I suck it out of the tank? is there a way to pull the hoses without leaking any? any ideas are really welcomed! Thanks!

620ie should have "quick disconnects" on the fuel lines, right at the tank, a little slider where the fuel lines meet the tanks, you press it and the fuel lines come out, a valve on the tank side closes when you pull the lines out, and all is good... So you should be able to disconnect the lines there an pull the tank to put aside for later.

Sometimes the valves at the tank leak a little, which is where you'll need to decide between putting the tank aside somewhere safe (outdoors) on it's side (half full) so the remainder of the fuel doesn't spill out, or stabbing at the valves in the tank (actually fuel pump) with a blunt object to try to make them close off..

620's have no qd's from the factory.

There are 4 lines. The 2 smaller diameter lines will have no fuel in them.

The larger lines are the feed and return. There should be a decal on the tank listing which is which. The feed will have fuel in it, but not much will drain when the line is removed. The return will spew gas everywhere if there's fuel in the tank.

as DP said, no quick disconnects. but this is your opportunity to add them if you want.

I was not able to do it without getting gas all over the place.

I'd take this opportunity to put some quick disconnects on. It's much easier if you plan on working on your own bike.

Got mine offline from a company called Coulder. They weren't cheap but they are well made.

hi! by any chance could you provide me the part number of those colder quick disconnects? Thank you! will they fit my 620ie?

[lazylightnin717]

I've since deleted the email I received from the company's contact regarding the part number.

All I did was shoot them an email asking for 2 sets of quick disconnects with valves and suitable for the proper ID of your fuel line. Mine was 5/16" and I doubt yours is any different.

I'm sure these would work for you. The hardest part was finding a spot to put them.

If you look really hard, I put them right above my clutch where the fuel lines were originally run. It looks great and allows me to take my tank off in a matter of seconds without making a mess.

Those same disconnects will fit your bike.

Sweet ride you have! yeap I have same hoses... ok, will order them after I check my local hose store, maybe they have a pair like those too... thank you so much!

You have to very careful not to kink the gas lines when you have them installed.  There is not a lot of room to fit them in.

Saw this company just now.

MotionPro sells plastic QD's from Colder:

Those are the dual shutoff version.

Single shutoff versions are a bit cheaper, but you must have the 'shutoff' fitting connected to the tank.
You'll still get a bit of leakage from what's in the lines and injectors/pressure regulator, but it's not a lot.

i have these on my bike, and they work well. only issue i have ever had was that the o-rings can get pinched/torn if you are not careful when re connecting
