gas tank strategy

    My '14 FXST has a balance tube at the underneath the front of the fuel tank. Rubber hose is semi-permanently crimped to the nozzles protruding under the tank. If I wanted to remove the tank at home, I suppose I would syphon most of the fuel out, and then use pliers to bust the crimped fittings on the balance tube, and use a longer piece of rubber hose to try and capture the remainder of the fuel.

    When I replace the tank, and the balance tube, would it be satisfactory to use the re-useable hose clamps (the type you tighten with a screw-driver or wrench)? 

    What if I was travelling somewhere and needed to remove the gas tank? Should I carry a length of syphon hose, couple hose clamps, and a new balance tube? I would need to be careful not to splash gasoline onto the hot engine. Maybe let the bike cool for an hour.

    Can anybody with experience provide thoughts and comments please on these scenarios.

    In my travels I tend to leave the fuel tank attached to the bike.
    As FB asks- what's the purpose of all this?

    Mmmmmm, the crimped fittings you want to bust are reusable.. or they used to be.

    - There are clamps that you can use to seal the tube and then cut it in the middle and then pull off (some tanks are SOOOO tight over the backbone that you have to remove even the hose and clamps - you will not know until you need to remove)
    - Use normal stainless hose clamps rather than the OEM crimps.
    - The odds of removing the tank on a trip a sweet FA so do not overthink this chit.
    - I tend to run silicon hose over rubber, buts that just my preference.

    I'm just one of those people who like to know what is involved. I'm sure one of these days I'm going to need to remove the tank.

    I got tired of fucking about with that and got one of these.

    how often do you take off your tank to get tired of fucking about with it??

    I have had the tank off to fit an aftermarket fuel gauge,  swapped pistons and heads a couple of times, and removed the rockers for some work to quieten them down a bit.
    Only have to do it once with a quick-disconnect to realise how much easier it is.

    I Took mine off  when I did my cam chain tensioners and 
    a. put a new piece of hose on (2002 Ultra = 20 yo hose)
    b. Used 2x GOOD QUALITY worm drive hose clamps. Not cheap shit ones. 

     No dramas 2 years on.

    Just want to know what is involved if I need to remove the tank. In the old days you just turned off the petcock, grabbed hold of the tank, and yanked it off. Modern bikes (and cars) seem to like to make things complicated.

    That's an answer I wanted. Thanks.

    Its EFI I presume.  Be prepared for the quick connect fitting on the tank to leak petrol once disconnected - the seals in the connector go and can be replaced.  I just did an entire tank replacement on the Sporty so the pain is fresh in my mind.

    They look pretty snappy, why are they not suitable for fuel pump tanks?.

    q/r conectors like this are usually for low pressure transfer pumps not high pressure fuel rail pumps  [efi]

    I had one of those and it started leaking after a while

    Harley fuel lines to injectors are up to 60 psi, but the balance tube or crossover tube where they are used  is low pressure.
    They are obviously not up to the task in higher pressure situations.

    I have recently noticed a smell of petrol when I take the cover off the bike . 
    I  had a half arsed look but cant see anything obvious.
    It might be time to replace some of the fuel hoses I am thinking. 2002 fatboy.
    I watched steelos video but got a headache  about two minutes in.
    The rubber gasket / membrane / liner thing on the inside neck of the tank looks a bit dodgy. Anybody had that issue before?

    I'll be darned!, did not know the fuel pumps had to run those sort of pressures.
    Only taken my tank off once in 13 years and can't remember why I had to do it.
    Would have taken it off lots more if it wasn't such a palaver.
    As 009jim said, the old bikes were so much easier.
