ISR Performance OE Replacement RWD SR20DET Side Feed Injector O-Ring Pack inc FPR

Any time the fuel rail comes off a Nissan RWD SR20DET, the injector O-rings should be replaced, and this ISR Performance OE replacement side feed injector O-ring pack gives you a complete set for the job, including the O-ring for the fuel pressure regulator (FPR). Side feed injectors sit inside the rail and rely entirely on their O-rings to separate fuel from the intake, so worn seals are a safety issue as well as a performance one.

What the pack covers

The SR20DET side feed setup uses O-rings above and below each injector to seal fuel within the rail and to seal the injector to the manifold. The regulator mounts to the end of the rail with its own O-ring. All of these are included so the rail can go back together fully resealed.

Pack details

• O-rings for the factory side feed injectors
• FPR O-ring included
• OE replacement specification from ISR Performance's seal and gasket line
• Also supplied in the ISR complete S13 SR20DET gasket kit

Fits

Nissan RWD SR20DET with factory side feed injectors and rail, including engines upgraded to larger side feed injectors that use the same O-ring sizes.

Install notes

Lightly oil each O-ring before assembly and press the injectors in by hand with a twisting motion so the seals are not pinched. Pressurize the system and check for leaks before starting the engine.

All ISR Performance products are designed for off-road use only.
