do you make a back pressure gauge with a boost gauge and copper tubing instead of plastic or does a company make one

 

for back pressure that would be fine. where are you puttin it? if your making a drive pressure gauge you need to coil the copper half a dozen times or so to take the heat and soot out before getting to the gauge

 

that was another thing i know about coiling it for heat and soot but im not to kean on an exhaust line running into my cab

is that somthing to worry about or does the coiling stop that

is there some kind of isolater or sending unit that stops the line in the engine bay

say i ran a digital gauge where all i need is an electric signal sent in the cab and not a pressure line



any info?
