i d like to fit a fuel gauge to my xvs

so far only thing that i can find that looks like it may be of use is this

what options are there fit a tank from a different bike that has a fuel gauge or there some kind of universal gauge that can be fitted

A capacitance fuel sensor would work in pretty much any application. This one is capable of digital and analogue output and has a GPS tracker which screams lower insurance premiums to me:

I like the simplicity and look of the old school sight glass personally:

That Jim Beam one is so cool. I'm not a big fan of old school personally but sometimes it just seems perfect

The bottom pic is available thru Flyrite choppers and you could easily substitute the pipe for something similar and cool as the Jim Beam bottle, with a little sealant of course.

i guess that fuel sender with gps isnt cheap ( i can see a price in th ad)

the jim bean pipe an bottle does look cool

does anyone have any info on welding in the bungs on a used tank even though the tank would be empyty there is still going to be fumes

Why have a fuel gauge? cant you take the cap off and see what fuel you have or get into the habit of refueling every so many miles.
