We have no fuel gauge so I need to make one. Will a stick of bamboo with whipping suffice? Or is there a better, brighter idea out there? Your thoughts will be gratefully appreciated.
I inherited an aluminium bar with markings notched every inch or so along its length.
Doen't soak up diesel to continuously wick into the lazarette or introduce unneccesary moisture into the fuel.
The notches take up a little meniscus of fuel showing the level quite well and the whole thing wipes dry with a bit of kitchen roll that can be put in the take-home rubbish with very little diesel smell.
When I was an apprentice marine engineer I used to chalk the steel tape when dipping the tanks to show the level.
To avoid being misled by confusing old level marks while measuring two identical tanks, I made up a length of thin plastic pipe, and strapped it to a length of cane.
To read and see the level, you dip the cane into the tank, place thumb over the top end of the pipe, and lift up the cane.
A girt big shifter screwdriver I found on the boat when I bought it. Not graduated, but when the tank is full the level comes just to the bottom of the handle, so it easy to estimate what's in there by eye when you look at the 'wet' level on the slightly rusty shaft.
Best is any suitable rod with blackboard paint on, or the green garden plant sticks.
Ours is a square section wood rod with matt varnish and blackboard paint with notches at various levels. The locker top that we lift to get to tank top has a tape stuck under with litre markings against a line. Dip and hold rod against and gives exact volume of fuel in tank.
To obtain correct volumes, hubby used a Pela unit to empty the tank, noting carefully level changes as our tank is not uniform square. Once empty he used a 5 litre plastic can to fill the tank noting again the levels and marking the tape line accordingly. Tape is standard duct tape with permament black marker pen used.
Not only has this given us accurate volumes via the dip-stoick but also rated the auto fuel gauge. (30 pounds from eBay)
I now realise how fortunate we are in having a plastic tank which is sufficiently translucent to see the fuel level through. /forums/images/graemlins/grin.gif
I use a length of white plastic pipe (about 12mm I think) as it needs to be flexible to get to the tank in the first place. The markings had to be a bit technical as the tank is tailored to the turn of the bilge.
Lightly sanding the pipe and cutting the marks makes it easier to read.
Next question ~ where do all us dip-stickers hang the thing to drip after reading it?
This is the beauty of a stick instead of a tube... I can only wipe the outside! I will obviously have to block the bottom end up with something that will stay in place.
As to the calibration, it may be easier for some to mark it in hours x5 instead of capacity. I had both on my last boat.
