  • Regulator for custom build
I haven’t applied pressure or fuel to this regulator yet, but it appears to be of high quality and comes with various fittings and O-rings. Setting it up or installing it was quite straightforward. I’m thoroughly impressed with the product for my build and believe it offers excellent value for the price. ... show more

  • Seems good so far!
It has worked so far for initial start ups and feels like good quality. My gauge that came in the kit was not broken and was within 3 psi of Holley terminator sensor reading. Running N/A so not sure if the 1:1 referencing works

  • great value
Bang for the buck with this one, Boys and Girls, you will not be disappointed. Came quickly in secure packaging, packed in foam, and parts spaced from each other so nothing would get scratched up. Obviously, very well made soon as you pull it out of the box, you can feel the quality in the weight of it. Nice finish to it and easy to install with a properly made bracket, no issues with that. installed quickly and straightforwardly, easy to adjust. Have not run it under boost yet, but I have no doubt it will perform as it should. Great value on this one, don't hesitate. ... show more

  • DO NOT BUY! Don't risk your car on this cheap device
0/10 DOES NOT WORK! DO NOT BUY! My faulty 10+ yr old Aeromotive FPR does a better job than this. Our car leaned out horribly on the first drive. Watching the fuel pressures, you can see it's bouncing all over the place not knowing what the heck to do at idle or at WOT. Do not buy this, you will risk blowing up your car if you don't have an in-cabin fuel pressure gauge or a way to monitor the fuel pressure. A brand new Aeromotive unit was ordered and proved to deliver flawless fuel delivery. ... show more
