Radium Injector Seats for Toyota Top Feed Fuel Rails (20-0216 / 20-0848 / 20-0516)

The seat decides which injector your rail will accept. It is a small part with a big say.

These Radium Engineering injector seats for Toyota top feed fuel rails press into a Radium rail's injector bore and set the injector body the rail will take. The right seat is what makes a rail work with your chosen injectors rather than only the factory parts.

Choose Your Seat

Features

• Press-in injector seats for Radium Toyota top feed fuel rails

The Details

Seats are sold individually, so order one per injector. Note how close 19mm and 20mm are: a millimetre decides whether the injector seals, so check the injector manufacturer's drawing rather than estimating. The air assist seat serves Toyota engines running air-assist injection, which uses a different injector arrangement; moving from air-assist factory injectors to conventional aftermarket units means changing seats.

Applications

• Radium top feed fuel rails for Toyota engines

Important Notes

• Sold individually; order one per injector
• 19mm and 20mm are only a millimetre apart; confirm against your injector's specification
