In other words, they're all pretty small, maybe an eighth to three-sixteenth inch bore. Obviously engine oil won't flow through this like water. The vacuum pump versions can't deliver it as fast an electric pump would. Best used after a decent drive to warm it up

Many thanks.

I need to read the post properly as it clearly states in the first post it goes down the dipstick tube.
