Pump did not last three years because of an o-ring seal. They do not offer a simple seal kit and want $415 plus shipping for replacement assembly or send it in for a "rebuild". How can you rate customer service when there was none?

Great customer service! Very helpful very fast shipping! Awesome product! Before I found out about FASS fuel systems which solved my problems instantly, I replaced a lift pump about every two years. Now I have the new system installed with a lifetime warranty and I'm confident that I will never have to use the warranty!

Bad customer service. Don't speak to me like I don't know what I'm talking about. Even if I didn't know what I was talking about, which I do, you shouldn't treat customers like that. I'll do business elsewhere in the future.

I needed help with information on how to register the warranty on a lift pump and technical questions about the pump. Every person I talk to were very helpful and spent time in answering my questions. I would like to give a special thanks to Sharon for helping with the warranty. Thank you all!

I would like to provide better, however their efforts to assist are only based on income. Yes, of course any business would do so however these people were told about failures and claim it is impossible. WRONG....the FASS product fails yet they refuse to believe it. I had a titanium unit S# 17020....it failed 2 x (the spring and ball unit were defective in regulating psi) leading to replacement of a CP3 and thousands of dollars in repair costs at one occasion and an additional stranded scenario costing thousands again. NEVER USE A FASS

Justin always emailed me back the same day or even a couple times a day if I needed and seemed very knowledgeable about their products. Very helpful in my opinion. Would definitely recommend

Justin was amazingly helpful in helping me diagnose my issue. His attitude, demeanor, knowledge and patience were incredible. As far as Fass product's, I'm a customer for life.

Great customer service. Previous owner of my truck had a unit installed probably like ten years ago or so, and the tech support guys are always willing to help if I have a problem.

I had to call in to speak with someone about an issue I was having from a previous owner installing the system incorrectly. Quick phone call and I was able to fix my issue. I was very pleased with the custom service!

Great company with superior products. If in the market for a diesel fuel system, I highly recommend them.

Fass has the best fuel system and the very best customer service of all. Jarriel Scott is the greatest at his job was very understanding and explained every step needed to get my problem fixed.
