Possible. It was only around 3cm but still. I clean founts with acetone first, then dishwasher liquid, if necessary I then shake some steel balls inside it. Works ok for me.
Cheers @Matti Kucer ! Not sure where the acetone is at the mo and I don’t have a dishwasher so may opt for alternatives, but thanks for the advice Yes, that does seem a bit short for an improvised dip stick.. There was quite a bit of hair in with it all so perhaps some contaminated fuel on a farm or similar...
