I replaced my sending unit a year ago and it was definitely under $100! Makes more sense that it is leaking at the fuel pump. I made my own hard lines into the fuel pump by using steel tubing from Summit Racing. I think I used 3/8. I soldered it onto the fuel pump cover and it has been just fine! Bending the tubing can be a pita. I suggest that you also check the lines coming out of the fuel pump. Mine were badly corroded and about ready to break. I replaced all my fuel lines by fabricating them myself. Kind of a time consuming, frustrating job, but I sure saved some bucks! Dang stealer wanted $99 for each of the hoses with banjo fittings at the fuel pump <img src="/forums/images/graemlins/evil.gif" alt="" />
