[Shotimes] getting to the oil pressure sender

Well, technically there is flow every time the pressure changes. Think of it
this way. Lets say you have a 1/2" diameter 1 foot long dowel. You push it
against the wall with a certain force. If you were to take a 5 foot long
dowel and do the same thing, with the same force on your end, the force that
the wall 'feels' will be the same.

In a temperature sensor, you would be correct in putting the sensor as close
to the original as possible. Temperature dissipates over distance. Force
doesn't at very low flow rates.

http://www.42draftdesigns.com/installation/book1_relokits.htm shows a
relocation kit, which will work fine.

How can there not be flow? It just stops and freezes?
:)

Plus there are varying rates of pressure at different
engine speeds, oil viscosity, temp, etc...
