ok i will take a look at that , i installed this guage to replace a really cheap one. I may have gotten teflon tape in it or something.
i really do not understand it at all, fuel lines on the stock cars for many years ran from the fuel pump to the carb. right up the front of the engine and across the intake. I know it was a lot hotter there, than where mine is . I will look at the guage again, thanks for your help
