Product Details

The Standard Motor Products PR397 is an Intermotor Fuel Injection Pressure Regulator engineered as a direct OE replacement for import vehicles. It is designed to maintain consistent fuel rail pressure, ensuring the correct fuel-to-air mixture is delivered to the engine under all operating conditions.

Key Features:

  • Direct OE replacement design for precise fit and form
  • Precision-engineered to maintain stable fuel rail pressure for optimal engine performance
  • Robust construction for enhanced resistance to fuel leakage
  • Application-specific design eliminates the need for modifications during installation
  • Built to meet or exceed original equipment specifications
  • Part of Standard Motor Products' Intermotor line, dedicated to import vehicle coverage

The PR397 fuel pressure regulator is a critical fuel system component that prevents over- or under-pressurization of the fuel rail. A failing pressure regulator can cause hard starting, rough idle, poor fuel economy, and engine hesitation. Replacing it with a quality OE-equivalent unit like the PR397 restores proper fuel delivery and protects fuel injectors from pressure-related damage.

Best pricing I found anywhere on the part I needed, quick shipping, no hassle. Definitely going to be a repeat customer.

Installed a 5th wheel hitch in a F150 with a 5 1/2' bed. Autoplicity had the Sidewinder hitch I needed to put the swivel under the camper insead of at the hitch,also at a lower price than competitors with extremly reasonable shipping $14.38. I Placed the order on a Friday and the item shipped the same day. Very happy with the product and fast shipping.

Autoplicity had an item my vendor had on backorder for weeks in stock and shipped it very quickly. I'm glad i found this place on the web, and will be looking forward to doing business with them in the future!

Quick

Great prices, super fast shipping!

SUPER EASY TO ORDER, CHEAPEST PRICES!! WILL BE ORDERING FROM THEM AGAIN!

They had the product I wanted at an excellent price. I was very pleased because my order came much faster than I thought it would.

Its amazing the prices Autoplicity is able to offer some of their products at. The product i ordered was consistently msrp on every site i searched through, yet autoplicity had it for $10 less. Lowest price along with a attractive and intuitive website is a win in my book. Having it shipped in less the 24hrs is another bonus

Excellent service and the cheapest price that I could find anywhere. Ordered on a Sunday and delivered in record time three days later...basic overground shipping. I will deffinately order from here again!
