Okay, so I bought an 89 Chevy suburban that needs new brake lines, and fuel lines to be safetied. I have a couple questions. 1) I am pretty damned sure I can get stainless steel tubing from my old work for a good dealeo. Is this a good call? I am trying to keep the initial cost down. Should I just go with the standard steel tubing? Or is it worth my time, and money to go stainless? 2) What are the sizes of the brake and fuel lines? I know there is a send and return for the fuel lines, but I don't know the sizes. And I don't know the size of the brake line either. 3) Is this a huge pain in th @ss to do? or is it do-able in sub-zero (celcious, not farenhiet) temperatures. 4)The tubing comes in 20 foot lengths. is it going to be more then 20 feet per line? would I actually need to buy two lengths of this stuff? If so I will bite the bullet, if not thank you GM!!! 5) If anyone has done this, is there anything I should look out for?? -problematic areas? -clips that always rot out? -you have to be nekkid to do any work in sub-zero weather? Oh and P.S. I am doing this in a cramped gravel driveway... so I cannot get any jacks or such items under the truck.
