In the process of mounting my back pressure sensor on my car.

I am looking for some ideas.

Show me what you got.

What you after? I don't have any pics but... I put 1/8npt nipple in the pipe from the motor to the turbo. Ran some brake line (I think) and snaked it up to the firewall where I have the sensor.

Don't mount the sensor on the pipe.
We will weld a 4"~5" 1/8" nipple off the header or crossover and as mentioned steel brake line to the sensor of gauge. Use teflon braided if you need a flex.

how many coils/ feet are needed between the fitting and sensor?

I usually go 2~4 feet you might be able to go shorter.
A little longer allows less heat to the gauge/sensor.

We use a 6' length of copper tube we coil up and put stainless compression fittings on each end. Usually use a 1/8npt female fitting like this on the collector.

Bingo!

I did just as Shearer posted and used a 100psi oil pressure sender. Worked great for me.

Just FYI, there is no reason to use copper tube. Yes, it's easy to bend, but, all it's going to do is transfer heat down itself very effectively. If the goal is to keep the sensor cool, use something with crappy thermal conductivity.....steel...or better yet, stainless.

Long copper tube is probably going to be fine, but just sayin'.
