My fuel tap

[bemusedinsojo]

This is my fuel tap. Is it normal for the smaller tube to be collapsed like that? Also, something is rolling around in the tank. Does anyone have an idea of what it is? I can't seem to catch sight of it. Thanks for your replies.

There shouldn't be anything rolling around in the tank, get it out and see what it is. Also a good time to give the tank A GOOD clean out, don't forget to check the drain pipe.

It's not unusual for the nylon strainers to collapse. You can clean them and put them back but in my experience, after they've collapsed once, they do it again much more readily. So, two choices, put new strainers on, not sure if you can still get genuine or you might find other suppliers or my personal recommended method would be to bin them and fit a good quality external filter between the tap and the carbs. If you go with the external filter, removing the final filter hidden in the hose just before the T piece into the carbs is similarly recommended.

Search on the subject in the Steamer section for plenty of details on this subject.

Agree with Sin on that. Had two rides last year out to a Rally no probs, back from Rally, died after 20 miles, fuel starvation. Pulled both screens off and haven't looked back. Of course our petrol with added extras causes carb problems, but at least now the fuel gets a far as the carbs...
I to had something in my tank, but I knew it was  a tank cap mounting bolt, as I dropped it in myself.

Thanks gents. I'll remove the strainers. Speaking of the one between the carbs, is it in the fuel line itself or is it supposed to be external? I'm afraid that is a question with an exquisite lack of knowkedge but I am not the sharpest pencil in the box.
Thanks,

It's a fair question, it's stuffed inside the actual hose, unless it's already been removed.

It is gone. I just checked. Now to banish the other strainers.
Thanks.
PS how can I tell what size the carb jets are?

[London_Phil]

The jets should have the number stamped on them, either the top, or on the side, just below the slot for the screwdriver.

I found a data security chip rattling about in mine. It was glued in about 15 years ago and forgotten about, I replaced it on the underside of the tank.
I replaced my internal filters with an external one, the only problem I find is that if I run dry and have to switch to reserve, the bike dies and takes ages to get going again, with lots of spluttering and dying from fuel starvation. Even after I fill the tank it is still unhappy for quite a few miles. But I have no problem if I switch to reserve before I need to, only if the bike starts uttering on main supply. Not sure what is happening here.  Any ideas anyone?

I don't know but a good question in case I run into the same problem.

[Sin_Tiger]

Sounds like an airlock Geoff. Try repositioning your filter so that the inlet faces directly up, the trapped air should clear easier that way. I've find that some filters are better than others, perhaps a different type or make.

Wonder if the security chip still works after years in petrol 

[tonytiger]

Geoff take the tap of and try bowing compressed air through it [open and reserve settings] might work might not.

I had the exact problem on a different bike once, in that case it turned out to be a flake of paint settled on the reserve outlet 

[kenny junior]

mine was like that. I had an air lock on reserve so the bike would splutter and cut out on reserve. When i took it off to push it back out i did flick petrol in my eye so please be careful of that and not do it right in front of your face like i did

[London_Phil]

Please ensure your airlock is treated by a Triumph trained mechanic.........That's one in the eye for home mechanics eh......


Sorry
