old red metal fuel tank.

[blueboy758]

i have a few old red metal fuel tanks with a gauge on the top of them, i assume the needle is connected to a floating ball ???

can i convert them to a gauge i can use on the console, if so what do i need?

thanks again phil

No ..... not unless you could replace the float guage cap with some electronic float linked to a potentiometer in the tank .. have a google.... someone might just do that very thing .. it wouldnt be too difficult ........... getting a fixing to mate to your tank would be the hard bit

Not blowing up would be the hard bit too

Anything like that would need to be hardwired and disconnected with the boat isolated, which would make removing or changing over a portable tank quite difficult.

if you have portable old metal tanks, then I give you a very friendly advice that get rid of them.

They produce rust and it will go into your carbs no matter how many fuel filter you install.

My first boat had an Evinrude 70hp on it with a nice (but old!) metal fuel tank. Once I started cleaning the carbs and saw a lot of red metal rust there. Checked the tank itself and it was also full of rust at the bottom.

right i'll probably do that then, does anyone recommend a tank to buy that would fit a gauge? i think i fancy a 40l tank??

I've got a 12L plastic tank branded Quicksilver which came with my Merc Sailmate 4hp, not sure if they do a bigger version but that has a gauge built into the filler cap which appears to work well.
