DIY Fuel Injector Refresh and Service

DIY Fuel Injector Refresh and Service

The same process can be used for many other TOYOTA and LEXUS vehicles. This video does not show cleaning and flow testing the injectors, but it does show you how to gain access to them.

PARTS LIST
Fuel Injection Pulsation Damper (2). I just went with the Standard brand. OEM would be ideal, but they are very expensive and I don’t like the diaphragm screws in the top of the OEM versions.

O-ring and microbasket fuel injector kit. https://www.ebay.com/itm/264683925517

OPTIONAL
Fuel Injection cleaning and flow testing. In the past I have had good luck and service from WitchHunter Performance: https://www.witchhunter.com/ (keep in mind if you decide to get your injectors serviced, you won’t need to buy the o-ring and microbasket kit in the PARTS LIST section as that should be included in the service).

Lower crush washer (between banjo and fuel rail inlet port. OEM P/N: 90430-12026

Upper “star” washer (between banjo and damper). The replacement damper came with two new ones, but they’re very thick so I just reused my OEM washers with no issues.

When I need to do some maintenance on my GS, and not quite sure how to go about it without making a mess of things. You have the video I need and in clear exact instructions on how to get it done. Fantastic video man thanks.

Hey man I’m looking at an 03 GS430 for $5k.
He has replaced distributor plugs, spark plugs,water pump, timing belt, radiator and hose, outer tie rods, rotors and pads. Is this a good deal? Thanks
