Wrong fuel pump???
Ok, I noticed quite a bit of fuel in my oil the last time I changed it in my 66 w/ the 240, so I went to O'Reilly's and ordered a new fuel pump. Changed it out with no problems. The truck runs fine when you can start it, but thats when you can start it. Now I have fuel pouring out my carb and it floods like I have never seen. Even with the choke all the way closed, gas goes everywhere from the base of the carb. Did they sell me the wrong pump? Thats the only thing I can think of, it looked like my old one more or less, but is it kicking out way too much psi for my little single barrel carb? Any thoughts??

I doubt its a pressure problem. Most mechanical pumps are like 8 to 11 psi. What probably happened is when you removed the old pump some trash got in the line and pumped into the carb. This is real easy to do if you have one of those pumps with the filter built into the housing. They have what looks like a small can screwed on. I have that type pump and I have decided to add a filter after the pump. A decent size piece of trash can hold your float needle open and cause your flooding condition.

Thanks for the tip, I took the carb off today, and cleaned it. Since I had it off I did a quick rebuild. Hope to have it on tomorrow and I'm optimistic it'll fire right up. I think I may steal your ideal and put an inline filter behind that pump, seems like a good one to me.

the fuel in the oil most likely came from the carb running really rich.
