The fuel line is not near the header as right below where you see the fuel line on the pass side fenderwell is where it comes thru the inner fenderwell as it runs up by the rocker panel and I drilled a hole for it to come thru the inner fenderwell. It does not run up along side the header tubes. I put it like that to keep it away from the headers. My buddies 65 does the same thing but his fuel line is closer to his headers I believe. It did it last year without the heat shield but I had the phenolic spacer on it then. So basically the shield made no difference. Ron
