Customer Guides

A dozen things can go wrong with your vehicle all because of a busted fuel pressure regulator. The spark plugs may be filled with soot and will appear black, which could mean that there’s burning oil at the head. The tail pipe may emit black smoke as well. There could be fuel leaking into the oil system, resulting in the oil dipstick having the smell of gasoline. There could also be fuel leaking into the exhaust, leading to fuel dripping from the tail pipe. With a faulty regulator, the engine may stall and fail to run smoothly like before. As you replace the stock regulator to fix all these issues, you have to find one that can meet the requirements of your vehicle and match its specs. We picked the AEM fuel pressure regulator to see if it’s a reliable option for replacement. Here’s what we think:

Features

  • Sold individually
  • Adjustable
  • Anodized black
  • Direct fit
  • 20 psi to max fuel pump capacity
  • CNC-machined
  • Made from 6061-T6 billet aluminum
  • For gasoline fuel type
  • Comes with -6 AN in inlet size
  • Features a female thread inlet
  • Stock return type/outlet size
  • 1:1 ratio
  • With AEM limited warranty

Pros

  • What we like about this adjustable fuel pressure regulator is that it can provide fuel flow support even for engines that can generate up to 1,000 hp. It can be used in racing applications.
  • The regulator’s output can fit into the output of any fuel pump because of the interchangeable discharge ports.
  • The regulator is made from top-quality material, making it sturdy and highly reliable. It’s CNC-machined from 6061-T6 billet aluminum. You can see in its material quality and finish that it’s made to last. It won’t break or leak easily.
  • It fits perfectly. We didn’t have any problem with the inlet/outlet specs of the vehicle where we installed the new regulator.
  • The adjustable regulator can be used on other vehicles. We tried installing it on another car, and it’s able to adapt easily. It has a good adjustment range, from 20 psi to maximum fuel pump capacity. We didn’t need any additional part just to install it.
  • The high-volume adjustable fuel pressure regulator comes at a good price, given its quality, flexibility, and performance.

Cons

  • Others have complained that the box may have missing parts and that some delivered items didn’t match the specs.

Conclusion

It’s well put together. What we have here is a high-quality fuel pressure regulator that can do the job in sustaining the needed fuel flow and maintaining the pressure to do so. It’s reliable and flexible.
