On a different note, if you got the pressure switch from Speedway it has been recalled as they where tracking down customers sending them a corrected switch, got one in the mail a few months back without any notice, I have the one Roger listed first on my '32 and haven't had any problems, on my 37 I went with the low pressure switch from Speedway (thus the recall notice) I used it because we had one on a '65 Ford pickup that lasted 30 years with not a problem, I figured my mechanical switch would go bad before that (of coarse then the Speedway recall!)
