Dump the light and fit a reserve tap on the petrol tank.

It doesn't have a tap, it's EFI.

That only makes it more of a challenge to fit one.

Bored today, so,




Magnetic ring at the bottom of the float.


Cut down alloy cigar tube. Just the right size to let the float move freely up and down and yet thin enough to fit the mounting hole in the tank.


A small hole to let fuel in and out and a similar hole on the top to prevent air locks.


So now the float can only go up and down at a speed controlled by the size of the hole.

Brilliant

It’s even topical too...... Corona cigar.....

That's neat. Just for the record a common fault with the fuel sender in an EFI RE is that the ethanol in the rubbish fuel we endure these days attacks the plastic, ultimately dissolving the float. This is a bigger problem in the USA where they've had 10% ethanol for years. Whether it affects the later I've Euro IV bikes or not I don't know.

That's brilliant Haggis!
Trouble is, I don't smoke or know anyone who smokes cigars

Still only 5% ethanol in uk so not seen any problems, yet.
Just for info, the outside of the float is 18mm, the inside of my cigar tube is 19mm and the outside is 19.50mm.
Rather than permanently bond the tube to the sensor I made a small spacer from an alloy crush washer.
This a tight push fit on the sensor and is a nice push fit for the tube.

Thanks Haggis, nice little project. Does it work?

[Mann]

Thanks for the posts everyone, i like the homebrew ingenuity but does it work?

[PeteF]

Been thinking about this, it doesn't need to be closed at the top?
Just a small hole a t the bottom?
I wonder if I can turn alloy that thin. I would need to make an arbour to support it I think.
Just going to the shed!

[Haggis]

Off course it works.
PeteF, your quite right that it can be open at the top but I though that a little hole the dome looked cool.
