maximum tank level without sending unit

i think im finally getting ready to replace my fuel sending unit
i think i have about 3/4s of a tank (though the gauge reads 1/2)

is that low enough to pull the sending unit without getting showered?
I just changed mine and 3/4 would be way to much ,drain has much as possible ,then when you lift the car ,have the front end a bit higher then the rear.if you didn't buy an nos sending unit be sure to use the original lock nut .the Chinese junk dosent lock to well.hope this helps
