Petrol dip stick material

[Howard Wright]

Hi All

Thanks for all the ideas.  Here is another one I came upon whilst browsing fuel dip sticks on t’internet.

Anyone heard of a “wine thief”?.  It’s a tube put into a cask, it fills up to the level of the wine. A finger over the open end prevents the wine from flowing out and the “thief” can be removed full of wine.

Here’s a very very rough first prototype Just to see if it works on the fuel tank.....and it does despite petrol having a low surface tension effect.  I’ll report back when I’ve got a better version.

Cheers

Howard
