Fitting a fuel tank gauge

I've got a 5m bombard Explorer with a 50HP Honda on the back.
It has a 30litre fuel tank in the bow locker which looks like this:



It sits at a bit of an angle in the locker with the filler cap at the top. Although I carry spare fuel I'm always worried about running low as I can't easily keep an eye on the level. So, I was wondering if it's possible to fit a fuel gauge in my instrument console and have a bob or something in the tank.

Would anyone know of a relatively simple way to install what is required here? I'm assuming the only option is a bob which extends down from the filler cap?

The fuel will slosh around - especially in the bow making a gauge next to useless.

Over a few trips I'd always start with a full tank, measure the NM done with a handheld gps, then top the tank back up to see how much fuel was used on the trip. After a few runs you should have reasonable average to know what your typical L/NM therefore range is. You can keep doing this to ensure you have an accurate running average.

My average burn is 0.78L/NM for example or 1.28 NM/L.

+1 on my current set up doing some wild camp trips I have a 43 ltr main tank and a 22ltr spare I find I get 60 miles out of the 22ltr with an every day mix of speed whilst sightseeing so 120 miles leves me with 20 ltr left over in the main tank as a get out of jail card at that point I'm looking to refuel.

Thanks, I came to the conclusion last year a gauge may be a bit hit and miss so based on this feedback I'll just shelve the idea and simply go back to checking the level manually and being mindful.

On my rib tank which was well hidden in the console no way even to dip it so it was just the guage in practise the gauge stayed relatively full for ages then suddenly dropped off at that point I just carried extra fuel as pikey Dave said sooner be looking at it than for it
