Having some trouble with the temp gauge install. The brass fitting 1/2" x 1/4" NPT also has a seat area were the prob mates to. I'm not able to tighten the temp sensor enough to stop the VO from leaking. ( autozone mechanical gauge) One possible solution is to drill out the seating area so the fastener will thread onto the threaded bushing further. Then I may run the risk of bottoming out the prob on the bottom of the brass tee. Any suggestions?
Also what are you guys using for approved clear VO line to check for vacuum leaks? Would like to place it permanently to check on the VO every once in awhile. I would like to place a clear inline filter before the IP but haven't found anything that will take the temps.
