The fuel line wont be an issue unless you are using more than 3/4 throttle. BTW steel line is less than $20 for enough to do an A body, I just got a roll the other day for our 67 Vert to replace the 5/16" since we installed an injected Magnum which doesnt need it now but it will get a built engine this fall after we have some fun with it. I would start with the kinked looking rubber line first and put a filter back by tank until you can afford a new tank sans grit, rust and crud. Just my $.02....
