Fuel filler drain blocked by spot weld?

[mspenz]

I'm sure that I've previously read on here about someone with a similar problem and there might be some sort of work around?
The fuel filler water drain is totally blocked resulting in various amounts of water dropping into the tank every time I re-fuel depending on weather (this is northern Scotland ) so I decided to take everything apart and fit a new fuel filter etc.
Problem being is that the metal drain pipe has a spot weld attaching it to the main filler and this is the exact point where I can't push my guitar 'G' string beyond from either direction .

Anyone managed to fix this without replacing the whole assembly?

Mike.

Hello MIke, I had a similar experience with my R1200R. I tried compressed air; I tried the plastic string you use in a strimmer. After a lot of trying, I managed to do it from the bottom upwards. But it took a few evenings of trying. I only noticed this when I read on another website about problems with rusting in the filler neck on lots of R1200Rs because there is no abdeckring to prevent water getting into the well and sitting there. I can only suggest you keep trying. RobA.

No alternative other than to replace it Mike ...had the same on mine, tried various remedies and none worked. Not a difficult job tbh (the spot weld corrodes inside the pipe and blocks the drainage).

Ok. Everything is in bits at the moment and I'm not going to re-assemble until it's fixed as it is a PITA to be honest!

Sunny Jim, did you have to buy a complete new replacement filler flange?

Thanks Rob, I've spent quite some time tonight trying to twist various gauge guitar strings through but without success unfortunately so unless I attempt something drastic I'm looking at a new filler flange

Cheers,

Mike.

I did both mine yesterday

I make sure they are clear every month or so

Firstly I check they are working by putting on side stand & opening cap, then pouring petrol from a jug down the hole & watching it pour out

I then stick some strimmer cord down the hole & 'rod' it gently

Then I gently blow compressed air up the drain pipe, very carefully

Finishing off with a squirt of WD40 to prevent any rust build up

Seems to keep it sorted on both my 1150's

Also if I'm away & the bike is parked in rain overnight at a hotel I always put the bike back on the side stand before riding off for the day & make sure it is clear of water, by monitoring the drain tube

It's a pain - but needs keeping on top of

If it's rust blocking it, have you tried filling the tube with some acid, something like phosphoric acid, should dissolve the rust, leaving the base metal intact, you may have to keep topping it up, over a few days!

Cut the steel tube above the blockage and attach new length of hose.

I soldered a new pipe on for a buddy who was heading away a couple of years ago it was fubar blocked

Cut off the old bit and soldered a dod of brake pipe on, I even curled it around the filler as per the original

and gently drilled a concave into the opening up at the top

Blockage free for many years now

Combination of wd40 soaking, blowing back up from hose end, poking with wd40 spout, lots of bad language, don't give up!

It's absolutely solid and even compressed air won't go through! I'll have a look at maybe cutting and soldering as suggested and also check the new price, at least if you start out with it in good order it's more easily kept that way as per JB.
Thank's for all the advice
