It's pretty terrible, like 15 mpg, and it deosn't matter if I drive it on the highway or around town, the mileage is the same. Of course, when I got the truck it wasn't running very well so I don't know what it got with the original carb. Mine is also automatic with air and PS so that makes the mileage a little worse than it would be with a manual. Honestly I think it runs a little rich because it was fouling plugs real bad when I first did the conversion. I tweaked the float level and added a fuel pressure regulator and I haven't fouled a plug in about two years but I still feel like it is rich. I have also had trouble with flooding because of the electric choke, when restarting after a trip into a store or something, the choke closes just enough to flood it.
Honestly the mileage is why I have quit trying to fix it up. I could be driving a full size 4x4, which is what I really need anyway, and get the same mileage and better performance. My RAM 50 is a slug on the highway, even with the weber. It really struggles to stay at 70 mph. My advice, if you plan on driving it a lot, would be to find an engine and computer from a later model that was fuel injected and drop it in. The weber seems to be a good fix if you just want to get it running and have it as simple and easy to work on as possible. It does eliminate a lot of BS in the engine compartment.
