Repair cost

$300 to 500, depending on costs of parts. Labor for this is fairly low, it's the parts that cost a lot. Call up several shops in your area, you will need to know which of the two lines you want to replace (one is a high pressure line and one is the return line). Try Google for pics or ask a clerk at any auto parts store to identify the part. A local mechanic will be cheaper than a chain store (big chains like Goodyear, Firestone, Conrads, etc can be very $$).
