Bought a TS-D07-165G from a local dealer. Upon opening the box, I was VERY intimidated(cutting your fuel line is an uneasy feeling). However, FASS made a very great tutorial on Youtube. In the middle of installation, I got a little wild with the Dremel and put a gouge in the sending unit where the gasket sits. I called the tech support line and spoke to Jarriel, who took a lot of time to look at pictures of my mistake and help me find a solution without spending $500 on a new sending unit. He also gave me a few pointers for the upcoming steps. Jarriel even reached out the next day to make sure

As a diesel performance shop we work with many manufacturers around the country. I can't say enough about the team of experts at FASS Fuel Systems! They have given us an amazing product that is backed by possibly the best customer service in the industry. We have very few issues with the FASS Product line, but on the rare occasion that we do have a pump quit working, they have always been eager to make the situation a pleasant experience.
