Default Carburetor question



I’m wondering what kind of carburetor this is and where the fuel filter is. It’s a 76 corvette that is bought recently and the previous owner didn’t know anything about it.

It's an old Barry Grant Road Demon Jr. 525 intended to be equivalent to the Holley 4160 single inlet carbs. It does not have a real "filter", but may still have the Demon-installed inlet screen just inside the fuel line banjo fitting. This screen is not a very effective filter, so you would be well advised to install an in-line filter prior to the carb. The carb itself is small, but not a bad carb: It has annular boosters, which are very good, and externally adjustable floats, which are much better than its Holley counterpart carbs.

And, if you install an in-line filter, make it a metal one....not plastic or glass.

If you send me an e-mail request, I can send you a paper on how to build an all-metal line with an in-line filter. In the meantime, just pull out the inlet screen from that Road Demon carb and clean it out and blow it out.

I ran the same carb on a Ford Cleveland 351 4V back in the early 2000's. It was a decent working carb and worked better than the Holly it replaced.

This is a Lars line I build many years ago.
