Throttle Body for 1991-1995 Chevy GMC Truck 350 5.7L TBI – Direct Replacement

This 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. We may substitute another style TPS sensor with an adapter harness to work as shown in the pictures on this listing.

There are several different variations of the 350/5.7L TBI used over the years. There are 2 different styles of throttle position sensor (passenger side) and 2 different styles of throttle linkage (driver side).
