Detailed Description

Standard Ignition PR7 is designed to regulate fuel pressure in the injection system so the engine receives fuel at the correct pressure for proper operation. Robust sealing design helps resist leakage, while the precision-engineered construction supports accurate fuel delivery. This part cross-references Dorman - OE Solutions 800-121 for the same application.

Use PR7 when servicing fuel pressure concerns on vehicles such as Chrysler Daytona, Dodge Daytona, and Dodge Shadow. It also applies to other listed Chrysler, Dodge, and Plymouth models from 1986-1993, including 1987 Chrysler Daytona with intercooler and 1987 Dodge Daytona with intercooler.

What It Helps Address

• Fuel pressure that is too high or too low
• Hard starting caused by unstable fuel delivery
• Rich or lean running conditions related to pressure regulation
• Fuel leakage at the regulator sealing surface
• Driveability issues tied to inconsistent injector pressure

Installation Notes and Tips

Verify the vehicle application and fuel system configuration before installation. The straight nipple orientation and included O-ring should match the original regulator layout on the listed vehicles. Follow the caution sheet during service, and confirm fuel pressure after installation to ensure the system is operating at the specified 55 psi.
