1970 GTO V3

I like to repurpose OEM parts as part of my builds. I am not sure how I ran across this part, but it is from a 2008 Ford F250 with the PowerStroke engine.



This is what Ford uses for the exhaust pressure sensor, and I figured I can use it for the same purpose. In this picture, the tube has been cut and a sleeve installed over the cut. The sleeve ends where the green tape is and where my finger is pointing.



This is the sensor part number. From what I have been able to gather, it is a 0-54psi sensor.



The tube is stainless and 5/16" diameter and it uses 37 degree flares with tube sleeves and nuts at both ends. That size tubing translates to an -AN5, which is not super common. Luckily, I had this 90 degree NPT to -AN5 adapter that I was using on the old tank for the return line. The NPT side has been cut off and Vic turned it down in the lathe to make a -AN5 male weld fitting.



Here you can see where the fitting is going to go. Yes, the first hole was way off...



The whole assembly is bolted to one of the holes on the back of the heads...



and the tube extends down to the crossover pipe...



Once the tube was the right length and clocked correctly, the sleeve was welded to the tube.
