CHEVY GMC 87-90 350 5.7L TRUCK SILVERADO TAHOE SUBURBAN TBI THROTTLE BODY

This Rochester TBI unit has been rebuilt using a rebuild kit consisting of all new gaskets, new viton orings, new injector filters, and a new fuel pressure diaphragm spring. The injectors have been ultrasonically cleaned and fully tested prior to assembly. Once the injection unit is completely assembled, it is hot tested to check the function of the fuel pressure assembly. This TBI comes with the gasket that goes underneath it (not shown). You will need to use your existing idle air control valve. You may need to assemble the upper injector housing onto the lower base unit.  We may substitute another style TPS sensor with an adapter harness to work as shown in the pictures on this listing.   We may substitute a horizontal TPS sensor in place of the vertical one shown. There are several different variations of the 350/5.7L TBI used over the years. There are 2 different styles of throttle position sensor (driver side) and 2 different styles of throttle linkage (passenger side). You will receive a unit that is the same as the pictures on this very listing. If you order the wrong unit, we are not to blame. This TBI unit comes with a five-year warranty for unlimited miles.
