Time To Pull The Pump (again)

Should I try the SeaFoam before pulling the sending unit?

I put in double the recommended dosage in the tank and kept it at that higher level for a couple of weeks and it cured my problem. That was many years ago and it is still working fine. Having no idea what condition yours in I would suspect that if Larry is doubtful it probably won't work as I know that he has seen yours.
 
Here you go Andrew, this is a picture of the assembly the OP sent me.
I hope he does not mind me sharing it here.
I think he is just a bit past sea foam working at this point :rofl1:

A little CLR and some metal polish and that will buff right out!

When the exterior is that bad chances are the inside is no better in my experience. It looks like a failure waiting to happen on a dark lonely road. Even knowing how expensive it would be I still would be inclined to replace the whole thing. Peace of mind also has value.
 
I am going to start running a SeaFoam mix just as a prophylactic measure. The tank has been dry for so long I am sure there is varnish buildup in there.

I cleaned it with little brushes, and picks plus I replaced all the hoses, filter and pump but yes, it was a shocking mess. It's a good lesson in why, not to store a bike with a near empty tank.
 
I am having trouble finding the motivation to pull the sending unit. I know it has to be done and I did manage to get the fuel pump back in but I just have not lifted the tank. It's cold out there right now and I have become something of a wimp preferring my warm comforts.
 
I did pull the windshield and the front cover so I could access the the plug for the ECM. I wanted to make sure that the IAT Sensor was making connection to the ECM through the connector from the IAT. I have been getting a FI nine flash error code and I want to make sure the connection was good. It is good. I did replace the IAT sensor but without change. If the FI light continues I will put a piece of tape over it.

To anyone who has pulled the fuel sending unit from the upper tank, is there room to get it out without removing the tank? It seems that it will be a tight fit.
 
Yes, very easy with an empty upper tank.
Just tie the tank back with some cord and Truckers hitch, remove the fasteners and lift it out.
No need to remove the tank.
It could have been done in the time it took to type this.

Oh!! Tie it back. YES! What a fantastic idea.

I did order a new O-ring and a new connecting pipe just in case. I was just worried because you can drop the unit but you need some room to fish the float arm out. I'll pull it out tomorrow.
 
If you have any questions, give me a call before you start, I'd be glad to help you.

I understand, I used to have everything memorized, and a quick scan of a service manual was all that was needed to verify things, as I get older I don’t trust my memory as much, and check the manual often, just to be sure.
So far I’ve not had any issues, but I just lack trust .your not alone out there my friend.
We tend to start forgetting things we don’t do often, or that aren’t important to us anymore.

It's weird. I lose track of tools. I drop things. I look at things, like my forks, that I know need to be rebuilt and I think "I really don't want to get into all that right now." I know it's not easy but I might drag, what should take a couple of days with parts, into two or three weeks of puttering around.
 
You just need a motivational chat on the white courtesy phone :WCP1:
 
I got the fuel meter sending unit out (not a problem) but getting it back in was another issue. You have to work against gravity. I was installing a new O-ring and that flopped around a bit until I realized it fit neatly in the bracket indention. I expected the issue to be with a dirty reastadt. Turns out it was an issue with the solder joint at the terminal block. A quick re-solder and it checked out fine. I guess a few gallons of fuel is in order now to check my seal and to see of the gauge reads anything at all..
 
I am pretty sure I failed. I got the upper tank fuel sending unit out and in. I poured about a gallon if fresh non-ethanol in and the resistance on the sending unit lead went from .21 Ohms to .15 Ohms. Plus no leaks so far in the upper or lower tanks. Plugged the battery back in and I get flashing fuel bars and no change in the number of bars. I guess I did nothing. It's not a huge deal but I wanted it to be right. My guess I am still going to get the 9 flashes on the FI as well but we will wait until tomorrow to see about that.
