Here's some pics of the TBI (post rebuild)...

If one decides to rebuild the TBI use a Dremmel and some brass brushes to clean off the old gasket material. I went thru 3 of the brushes. Use safety glasses. Also be sure to coat all the new paper gaskets with Chapstick (both sides). This will prevent them from sticking.

What you see on the inlet side (left) is a fuel adapter fitting. It replaces the OE one and has a plug on one side and a fuel schrader valve on the other. Allows me to hook up quickly a fuel pressure kit.

An alternative to the Schrader is to install a gauge.

I modified the intake throat on my 5.7 TBI as well as adding a literal dog bowl between the filter housing and the TBI. Also got rid of the resonator and ran a straight 4” tube over to the fender.
