So I'm planning to go Carbureted

The purpose of this subforum is for someone to take a swipe at carburetion, which is okay, and is allowed to stand, then to complain when someone responds.

Fixed for accuracy.

Unlike EFI guys, we (carb trash) like drama. I welcome all white trash comments.

I keep having sync loss issues!

It's been about 3 years, but in an issue of Hot Rod, someone mailed in a question about carbing a Fox body Mustang (80's-early 90's 5.0) on the cheap. In the reply, they mentioned keeping the high volume EFI fuel pump and using a fuel pressure regulator to keep the 8-9lbs of pressure (or whatever is needed) and using the stock return line for the bypassed fuel. Since I can't remember the issue it was in, the brand they suggested slips my mind, but I remember it was something you had to call the manufacturer and order since most regulators are made to regulate high pressures or low but not in the way the one they used was. Seems like using a regulator like that would be the best way.

You can get low pressure electric fuel pumps (even rail mounted) for 20-30 bucks.

The low pressure required for a carb is the one big advantage I see of going carb. A regulator with the OEM fuel pump should really make that pump run forever. Current draw of a regulated OEM pump should run close to a low pressure pump. So if you have a working fuel system why not leave it.

The two disadvantages of going carb are less MPG (your mixture will change with altitude and other variables) and non-regulated idle speed (AC on, cold engine warmup, etc).

We have a fast idle thingie that can be set to make it idle high until the engine is warmed up. It works very nicely. We do loose a little gas mileage yes, but its a trade off I'm willing to accept for reliability.

Whats funny is in some instances I get high gas mileage compared to a poor running K-Jet system. Properly tuned/running K-Jet or EFI should be us in gas mileage any day though. We would have to be complete idiots to argue against that.

Regardless of the fuel delivery option MPG is dependent mainly on the fuel available. I have seen the exact same car with a difference of minimum 5mpg due to fuel quality.

What would you consider high quality fuel versus low quality?

Personally I put Chevron in my cars, but if there isn't one around I'll use Shell.

Chevron is garbage if it has ethanol in it. A high quality gas is one that is 100% gas. When I burn ethanol I get as low as 20mpg. I've seen gas mileage as high as 28mpg (actually 30 twice but I have doubts it was accurate) when I burn 100% pure gas.
