Leaking Oil Pressure Sender

[octanetorque]

Evening all,

Any advice on the above? its leaking from the block side, it would seem. This is a new one for me so...

How to remove (is it just a case of unscrewing - should I drain oil first etc..)

How to replace (any methods - tape, grease etc)

Any special tools or anything else that I should be aware?

Many thanks in advance!
