K-MOTOR Adjustable Fuel Pressure Regulator – 6AN Return Style - Universal Kit

Needed an adjustable regulator for a new fuel injection system (Aces Killshot, which from what I can tell they still have some bugs to work out of their software👎) and although Aeromotive makes quality fueling components I just couldn't justify their price for a component that might not even fix my issue. So I went with Ktuned fpr. I already had the lines run when it arrived so I made my 2 hose connections put sealant on the Guage threads and tightened it into its port and started cranking the motor. Eventually I got my 6.3l 385 stroker doing something resembling an idle and looked at the gauge. The needle was pinned right to 60psi and didn't waver from that until I turned the adjustment screw down to 48. The regulator and gauge worked flawlessly and look to be made from quality materials very similar to Aeromotive. The problem with these gauges is when they get hot under the hood they usually start to dance, reading pressure inaccurately. This one does not and is worth every penny I spent and will likely again.

Overall product is good. 0 leaks. Currently on my 2002 is300 return line setup. Only thing I’m not a fan of is the whole unit is metal BESIDE the 1/4 barb for your vacuum feed. It’s plastic so if you accidentally hit it I’m very confident it will break.

This thing is amazing and works great been holding pressure great and had no leaks out of the gecko!I did tighten all the fittings before installation and I'm assuming they keep them all loose so you have to go through them all and ensure there isn't any leaks!

it appears to be a good regulator but, in my case I could not use it. This unit requires a vacuum line which my boat does not have. Had to get a new unit that could be adjusted with out a vacuum line. It was past the return date so I am stuck with it.

So far so good after install, well worth the money, really accurate

works great for my LS swap, holding 58 psi, no gauge vibrations! I would recommend. I was not paid for this review.

I liked the product at first.....then after 5 months starting to develop issues with this item

Nice quality unit feels sturdy and well machined. Should last longer than the engine. Overall works great and was easy to mount and adjust. A definitely nice upgrade to the factory pressure regulator.
