I have a vulcan mechanical FP guage on my steering column. Has anyone had any problems with it?? When I make a hard right or left turn it dips in pressure from 15-5 PSI. I think it might be the antifreeze in the line not sure but it's full. I can't check it till tomorrow cause I'm workin, but I was just wonderin. Preciate it

 

Sounds to me like the line is getting pinched. Not the best place to mount that gauge.
