Customer service is non existent , do not buy products from this company. They will gladly answer the phone to take your money ignoring the service after the sell. I tried to order filters , but they have changed part numbers so much they don’t even know what to sell me. The filters I did buy was slow to ship and turned out they charged me 10 dollars more than their advertised price on their website . I definitely would not recommend this company unless you enjoy being frustrated and pissed off

Pump fails to produce the advertised pressure. They told me they don’t know the the problem is and won’t fix it. They have blocked me from emailing them they have blocked me from calling them.

So the lifetime warranty means they just block you when they don’t wanna deal with it.

Have had the Titanium on my truck for 7 years now and contrary to some reviews the customer service has been outstanding. They've stood by their warranty and YES IT WILL FREE FLOW fuel if the motor stops, If you install the kit correctly. The bad reviews read as people who are afraid to admit they either installed it wrong or ordered the wrong fitment/hose kit.
