Hi, I know it's been asked before - but the fuel tap seems to be either a terrible design, or I've got something missing? Spindly little metal rod affair with no markings? When people have answered in the past with the positions, they say 'up, down, rear' is this the open end of the bar pointing up, or the pivot end (as if there was a plastic cap with an arrow on it). I've got the open end of the bar pointing towards the rear of the bike, and it smells a bit rich. When I collected it, I think it may have been switched to reserve because there wasn't much fuel in it. 1999 Sprint 955I. Thanks!

No, it was a serious question, I've never had an injection bike before, been riding since I was 9, built my first bike at 16 (nearly 40 years ago), and have had many bikes since. When I was low on fuel, and bike wouldn't start - a neighbour who has 6 bikes himself turned the 'fuel tap' to reserve for me! The fact that it was ridiculously inaccessible didn't even highlight the issue, based on where the rad cap and coolant window are situated. Just thought it might be another Triumph quirk.

I made 2 mistakes here (not the fuel tap):

1) That a Triumph forum would be a good place to ask an honest question.

2) That Triumph owners aren't a bunch of tossers that would take the pi$s out of me for asking said question.

I inherited my late husband's mint MK1 Speed Triple (which has a fuel tap), and he was the one that convinced me that Triumph Owners were nice people.

My bad, I'll get my coat.

Unsure where anyone was being treated poorly. OP posted a question which, if you come from carb'd bikes, it's an honest question. The photo was helpful, by the way.

A user posted an answer, that mystery fitting is the fuel pressure regulator. It's basically an inert valve to do what it's name implies. Again, if someone hadn't had a fuel injected bike, this would look alien. Plus you'd be cursing British engineering for placing what could be mistaken for a petcock, in a damnable location.

We're glad you're here Genny, and hope you stick around. Yes, some folks are sarcastic, but there's a boon of knowledge.

The question was so out of left field it didn't appear sincere.
Just to confirm, unlike the earlier carburettor equipped T300 series of bikes, there is no reserve fuel tap on the T500 series and later fuel injected Triumphs.

Genny - I hope you won't go away mad and deprive yourself of an excellent resource and the friendship of a great bunch of Triumph enthusiasts. It isn't surprising that some of us thought you were having us on, since Sprints (and most other liter-class bikes) have been fuel-injected for 20 years. No fuel-injected bike has a fuel tap, they are unnecessary and wouldn't handle the high pressures required for FI. Moreover, most people would consider having to remove the bodywork to access the fuel tap was more than a "quirk" and therefore that was likely a misunderstanding of the function of the part in question.

You didn't indicate that there was a problem other than "it smells a bit rich". If that smell is coming from the vicinity of the fuel pressure regulator, then it could be that one of the tank quick disconnects is leaking. Use the Search function and there are a number of threads that discuss this issue. If it is the exhaust that smells rich, that wouldn't be unusual when the bike is not fully warmed up. Any other issues, I'm sure numerous members would be glad to offer their advice.

Best regards!

It's OK, I don't give up that easily!

I know they have been fuel injected for 20 years, because mine is a 20 year old fuel injected bike - but it's new to me :) . My bodywork has been on and off about 10 times (also first time I'd had a fairing, and can't believe how inaccessible everything is!), hence the thought it was just another quirk.

I don't think there's a fuel leak, and I have only done relatively short journeys so far (getting used to the extra wheel!), so it would tie in with not being fully warmed up. The engine does seem to kick out a lot of heat, keeps my knees very warm - and the fan kicks in quite early. I'll see how it smells when I've ridden a bit further.

Thanks.

Yeah, those bikes are hot.

An easy partial cure is to clean the radiator cell by cell to remove dirt and gravels hence improving the air flow.
I didn't say quick though. It's time consuming.


Regarding the fuel smell, first gen don't have an O2 sensor so the idle richness has to be adjusted w/ a gas analyser and TuneECU (CO value).


Regarding the quick disconnect as referred above, there was a recall, so if you still have plastic one, ask a dealer to change them for free. Only male side.
Beware that the part that is provided by Triumph for the recall doesn't have a fuel stop though (as opposed to the plastic one).
edit: The plastic female fitting inside the pump plate is prone to brake so you may want to change it as well. It's documented pretty well on the forum. Beware the thread is conical.

I never felt the need of changing the other female one on my 955 (never broke) but you may do it as well.

Glad you stick around.

Genny, if you have plastic fuel quick-connects, there is a strong possibility the fuel smell is coming from a leak. The plastic fittings WILL break, it's only a question on 'when'. The grey plastic 90 you'll find tends to hold up okay.

Many threads on the subject. Do a search for the word, "Colder". They make the stainless steel fittings (and, they make the original plastic ones). The removal of the female from the tank plate is a bit of a feat, but there are several ways to do it.

HTH!

Running hot? May I recommend Engine Ice as coolant? My 955i bikes (I have three) run very happily around 185F using this stuff. Higher in traffic, of course.
