I am using the stock tank, and the line in the pan is broken somewhere. What options are there, pictures ? Not worried about it being legal if the rules require the tube being in the tunnel.

I'm using a \"stock\" tank too.....when we had the body off, doing the suspension & such...I ran a new \"stock\" fuel line thru the tunnel in the \"stock\" location.......

I think your best bet is going to fasten a long piece of tubing inside the car on the side the tunnel. and then couple it on the ends with fuel line when is goes through the front and rear of the body. Also use grommets to protect the rubber. I'm pretty sure that's what I did when I ran a stock tank in the front.

I run fuel line threw the car on the outside of the tunnel. You certanly do not have to run the steel line inside the tunnel

is the stock line in the tunnel adequate for a high compression motor?

Totally adequate. So is the stock fuel pump.
