    Hey guys! New here and new to Triumph bikes. I had a coworker sell me a 96 Daytona 1200 for a crazy good deal. It's been sitting for two years though, and after rust treating the tank I'm working on getting it started again. I get it to turn over fine but I am not getting any fuel through my lines. I suspect the cause is the fuel level sensor. The wires were old and snapped right off. I figured it wouldn't interfere with the normal operation of the bike so I didn't bother fixing it. Does the fuel level sensor interfere with the fuel sending unit's ability to pump out fuel? I don't see any other electrical connector to the tank but I may be mistaken (or it is missing). Please note that I am fairly new to the carb life. My last bikes were newer and FI.

    Appreciate any insight y'all can give!

    Hi Ork, welcome to the forum !

    Sweet ride, I had two of those Daytonas but in the 900 form. Awesome styling & paint too

    I just had the whole fuel pump assembly out of my 2018 Thruxton 1200R and it looked to me that the level sensor was part of the whole black magic of it all.

    I saw that your question was unanswered yet so thought I'd chip in, for what it's worth.

    I really just wanted to take the opportunity to ask you to post some pics of the beast !

    Hi, welcome and they were a beautiful bike. I have the trophy 1200 version.
    This is a carbureted bike with the fuel tank directly over the carbs, it does not require a fuel pump. The carbs are gravity fed.
    The only thing that controls fuel flow before the carbs is a vacuum operated fuel tap. It has 3 settings, reserve, on and prime. Res and on will only pass fuel if the tap receives a vacuum, i.e engine running and vacuum pipe connected. Prime is used to fill the float bowls without the need of a vacuum. If the bike has sat for a bit and the bowls have emptied use prime and only for a short time (on mine 10 secs is normally enough) and is not needed when the engine is running.

    When you use Prime the carbs rely on the floats in the carbs cutting off the fuel flow. If the carbs are in good shape, then no problem but if the float valves are leaking then not so good.
    You can run the bike on prime all the time, you just have to remember to turn off the petcock when you stop and park the bike. That is the way any non vacuum petcock works. Vacuum petcocks can be rebuilt but often owners just replace them with a manual petcock and plug the vacuum hose at the carb/intake. On older bikes the vacuum petcock is often the culprit when a bike won't start.

    @Orksonak Welcome to the family. You have some good answers already. But I fear if the bike has sat for some time it will need the system cleaning mainly the carbs. Good luck and do keep us informed

    Fuel filters may be blocked with rust and/or old fuel gum.
    Fuel pipes, same.
    Maybe vacuum supply not working, so try on prime setting at Fuel tap.
    Tap is also known to break at the back, take off and check tap operation.
    Warning, don't run battery down by trying starter too much as you can damage the sprag clutch and it is an engine strip then..
