What Carb do I have?

[ford4wd08]

It's a Motorcraft 2150a. Tag number was probably E57E-BA. Don't buy a rebuilt one, you'd be better off tracking down a motorcraft kit (CT-1466) and rebuild it or having it rebuilt.

One reason you're getting awful mileage is someone disconnected and put a vacuum cap on the enrichment valve; it must be running incredibly rich. Get a foot of 7/32 vacuum line and connect the enrichment valve to the port on the EGR spacer below it. If the enrichment valve won't hold vacuum, replace it with motorcraft part ce-106. Aftermarket enrichment valves are all over the place.

I know this is old, but I have a question. Was there an option on the 2150A where the enrichment valve didn't have a vacuum hose going to it?

My 2.8 in my B2 has cover for the enrichment valve with no vacuum hook up, but I have a plugged hose on the carb spacer below it. I am currently getting pretty bad mileage, I wonder if I put in a new enrichment valve and bought a new cover for it with a vacuum hose if it would work better?

I have no idea what any shade tree mechanic did on this rig prior to me getting it from my Granddad's estate.
