Sinister Diesel Fuel Filter Conversion Kit For My 2023 Ford F350 6.7 Powerstroke Install & Review 

Thanks 👊🏼

Yeah I’ve seen them. They are nice. 👍🏼

I doubt the noise is coming from the fuel conversion kit. If there was a leak the fuel lines would blow off.

​@DieselLegiance thanks. New to diesels. Was worried about my cp4 and fuel filter housing. Whole reason I did. Truck is running fine, just don't remember that noise before install. Appreciate your help

@haus734 Just run 1 oz of Hot Shot Secret diesel fuel additive every fill up and you will be fine. amzn.to/3WwEEO4

The WIX is a bad filter and I’ve brought this up to Sinister so they actually switched to a better Baldwin filter which I believe is a 4 micron as well. The goal of the conversion kit is to give you a stronger top with metal fuel line stems instead of the factory plastic stems.

And please use a Diesel Fuel Additive on every fuel fill that has Lubricity as an Additive to help protect your CP4 ... Hot Shot Secret Every Day is recommended. A CP4 failure is a $12K - $18k repair cost, and some dealers are not supporting this failure under Warranty as the dealer is reporting "the customer used bad fuel". Do any of us know the true quality of fuel at stations we fill at... Search RU-vid on this topic for more information. Note the number of Disaster Prevention Kit Videos

@louie3552 Already use that 👍🏼

Just saw this and I already ordered this unit. Thanks for the information. I ordered the baldwin version filter. Same thread just smaller diameter and height by milliliters. Hope it works.

What upper fuel replacement did you go with?

Found a upper filter mount from Black Market Performance (BMP) that mounts the filter on the Firewall, and gets the filter completely off the motor. Did not use BMP's "Cat" filter that came with their kit either as it is not a 2 micron filter as they advertise. Used the Baldwin BF 46228 as indicated above with BMP's firewall mount. Note that some Disaster Prevention Kits mount their disaster filter in this same firewall spot. I do not need a Disaster Prevention Kit as I replaced the Factory Ford CP4 fuel pump with the New DCS S&S fuel pump. I still use Hot Shot Secret Every Day additive every fill for the Cetane boost and and injector lubing & keeping the fuel injectors and valves clean. Archoil fuel additive is also very good, but I get Hot Shot by the Gallon which Archoil does not offer. Having the upper filter On or Off the motor is a choice, just make sure that the upper filter used is at least a 4 Micron "Absolute". I change my upper fuel filter every 5k miles with my oil changes, and drain some (5-10oz) of the lower Fuel Water Separator once a month to get any water out that may be there. Final note: There are now reports that dealers are now not warranting Ford Fuel pump failure work even if the truck has a warranty, as they are now saying that the failure was due to the "customer used bad fuel" which is not covered under warranty. A Fuel Pump Failure repair is $12K to $18K repair bill. How are customers suppose to know what the quality is of the fuel they get at stations........! The Ford (Made by Bosch) CP4 fuel pumps used in the Ford 6.7s were developed under European Diesel Fuel Standards. European Diesel Fuel is blended with more Lubricity that US Diesel, and diesel fuel is also the lubricant for the CP4 fuel pump operation. Also note the CP4 "lifter" can turn on the Fuel Pump cam (Bosch did not lock the lifter from turning like motor Roller Lifter for a Cam). This can send metal throughout the motor's fuel system (2nd design issue with the CP4). Chrysler and GM have the same issues as they went from the CP3 to the CP4 for their diesels. Be aware and stay on good fuel/ fuel filter maintenance, or your not going to be happy when the CP4 goes south. Lots of RU-vids on here about the above, and also the Cold Side Intercooler factory tubes splitting under boost. (Diesel Legiance: Did not mean to get to much into your RU-vid Page, but the group I am with is all about keeping our 6.7s running strong and safe. The Ford 6.7 SD is an awesome platform, it just has some flaws... that can be fixed. Replace your Cold Side Intercooler Tube with aftermarket. The Ford OEM ones are prone to (blow) split under boost. The "4 ply" rubber hose splits, and/or splits the plastic coupler that connects to the Intake. When they blow, you have no Turbo (therefore no power)). @@cbobcat57

Sorry you feel that way. However, the filter they did include (Wix) was not that good at the time but they have upgraded the filter they include to a better Baldwin filter after this video was filmed.

@@DieselLegiance ok glad to hear they fixed that. The wix brand blows my mind how guys buy them. Sinister is also not a good company. Just rebranded, Chinese import stuff painted blue. Much better builders who make their own stuff in USA. I say this as someone who had my “sinister fetish” first starting out.

@Dieseldickrick Most of what we buy any more these days is all made in China. The phone you’re probably typing on is made from China. Anymore, with our corrupt inflated Country, as long as it’s good quality, low price, and comes in at a good value, I’m more than happy to try it out.
