Hi!
I'm going to install just the cheapo sunpro electric oil pressure gauge onto my car.
Just for space considerations, to keep my stock switch also, I've got a little piping growth spurt to get it all out of the way of the oil filter.
Since both the oil sending switch, and the oil pressure sensor (with the variable resistance for the sunpro gauge) are closed, I presume, there's no place for air to vent. Unlike say the oil filter, where oil pushes through, rather than just terminating and stagnating there.
When I turn on the car, and oil rushes to the galleys first, won't it trap air in there, and oil will never make it to the sending units?
Here's my question: does it matter, and if it does, how do I fix it?
It might not matter. Even if oil never makes it to the sending units, the trapped air will still be under the very same pressure. It theoretically won't give the reading as instantly, as air is compressible, but "instant" is relative and the feedback will be quite fast enough for me, a merely human driver.
If it DOES matter, do I a) need to prefill the tubing and sending units with oil before wrenching them on, to the extent that it's possible? Or b) need to make sure they poke down and not up so that oil can drain into them and air escape?
