They kept sending me defective parts and had the nerve to tell me I need to have their parts custom made by another shop. So to replace the fuel regulator lines which kept leaking because the hard lines were made too short or too long. So I purchased strictly diesel fuel bowl delete along with AirDog 5g and their FASS/AirDog install kit. The kit I received was an old kit I did not know so I did what I could cut the 3/8 line and adapted with 1/2 barb but the 3/8 to 1/2 hose kept leaking. I emailed this company they told me the kit was updated and asked where I bought it. I told them from power diesels and strictly diesel replaced the kit free of charge and shipped it fast got it in 3 days. The delay was fed ex fault because during transport they misplaced it. If they had not I would have got it in 2 days. Anyways this place backs their product and it was a pleasure dealing with their co owner Dennis. I just wish they made full line of products because everything in my Cummins and Powerstroke would be replaced with all strictly diesel parts. I only give good reviews to companies that deserve it and strictly diesel deserves 5 stars. Do not go anywhere else. Trust me I had issues with XDP, sinister diesel especially and Kerma TDI. I only have diesel trucks and cars and I invest a lot into upgrading my vehicles. Wish I found these guys sooner would have saved me thousands. Great job guys stay the way you are!
