Hello all,
what type of fuel sample unit you use? Looking for a "low cost" version, high needle/screwdriver, larger cup. Something like this, but 500 USD is out of budget (need at least 3 units)...

I was thinking of making own with screwdriver and empty bottle, but no big success with sealing it in the bottom where screwdriver goes through the cup.
