I was leaning on it being a pressure line. Race cars get changed all the time I could see that car having a vacuum hand pump under the dash and a different fuel set up than what you’ve found. your trans mount looks great. I can’t tell if youvee already done it but I would suggest running a little brace on the bottom of the stock cross member on each side of the mount connecting the “sides” millworks does there’s like this and it makes enough since that it would make the mount a fair bit more ridged. fantastic progress on this thing! Keep it up!
Ah...good point. My wife hasn't always agreed with that like when she mentioned the shop "dwarfing" the house a couple houses ago...lol
