We would love to help you out in getting the TBI that fits your vehicle. You just need to send us pics of your existing TBI -both the passenger and driver sides of it- along with the size of your engine to us via the eBay messaging service. We will ping you back with the correct TBI to purchase.


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. 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). This has the 87-90 style TPS sensor. You will also need to visually match both the throttle linkage and the throttle position sensor on your own TBI unit with the one in this ebay listing or it may not work for you. 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.


In order to ship these without problems with the USPS, we fill the fuel line fittings up with silicone for shipment. You already have a set of those fittings on your TBI. You need to re-use your old fittings, they do not wear out.


This TBI unit comes with a five-year warranty for unlimited miles.
