Blue spring kit 2003-2007 powerstroke
I ordered the blue spring kit for the 2003-2007 6.0 powerstroke. it leaked and the adjustable jam nut kept coming loose causing my fuel pressure to constantly change. i removed it, cleaned it all and made sure all seals were correct, still nothing but issues. i tried to reach out to sinister diesel about this but they were no help.
EDIT- sinister diesel finally reached out to me and was willing to work with me. I exchanged the adjustable version of the blue spring kit for the standard version. It works great, like it should and I am much happier now. I changed my review from one star to three. I do think sinister diesel has good products, I just wish they were more willing to work with customers without customers having to leave bad reviews.

Coolant filter for my 6.7…
I bought the coolant filter for my 6.7 Cummins. The product is great and quick tip, I bought the WIX 24071MP filter to replace the 24070 filter that comes with the kit to allow more room to get a wrench under the filter. I did end up getting leaks in the shut-off vavle connections when trying to have them perfectly straight up. I called customer service and an american actually return called me within a couple hours. I was shocked. Great product, great service. I did pay for expedited shiping as they are on the west coast and I am on the east but it took them a couple days to fullfill the order before it went to shipping and then it still took 3 more days to arrive. I would not pay the expedited shipping again. All else is great so I still give a 5-start review.
