I was very pleased with the service from talking to the customer service representative to the delivery and instal. After several trips to local parts stores and finding frustration with uneducated parts people, I decided to do some research on my own and came across "Inline Tube". I have to say I am not a mechanic but mechanically inclined enough to do some things myself. After deciding to buy from a specialty company and wait delivery, it turned out to be the best move hassle free with no problems. I questioned the picture of the recommended lines as being what I needed for my '03 F250 SD 7.3. I decided to call before I ordered to assure I was ordering the right product. The customer service rep was more than helpful answering all my questions assuring that the lines were what was needed. He also explained to me that if they didn't work that the originals could be sent and custom made with the same bends...IF they didn't work! Again he explained all the options and made me feel better about ordering what was recommended. Order was received and with provided quick instruction guide, instal went smoothly and no problems to report. I would recommend this company and if question the product the customer service was friendly, helpful, and reassuring.
