carb problem
My son and I are trying to get granndpa's old 1969 f-250 4wd running again We got it running but we can't seem to stop a fuel leak on the carb. It has a 360 with a two brl carb. The problem is it leaks fuel around the acellerator pump on the frount of the carb. We put a rebuild kit in it and tryed two other acc. pumps but it still leaks when we step on the gas. Does any one have any advice?

Most likely the accelerator pump housing is warped. Take it off and run it over some sandpaper on a dead flat surface, such as a piece of plate glass. Just a few stokes will show you any high/low spots. Probably the screw tabs on the corners are pulled in, so they should show as high spots. Keep working it till it's uniform shiny all over the mounting flange, and be sure to finish off with some fairly fine paper to remove sanding scratches.
Or replace it...

Thanks for the input. We've already tried three different pump housings with the same outcome. We rolled the truck out of the shed so we can fit all the running cars in . It's getting close to 0 F around here in Minnesota ,so the getting to work vehicle's get first dibbs in the shed. If we get a chance I'll try the sandpaper trick. What would be a good replacement carb?

I assume that your truck does not have an automatic tranny, so finding a carb should'nt be as big of an issue. I would start looking around the local junk yards, and better yet ask alot of people about an older motorcraft carb. You might be suprised what others have no use for but for some reason seem to hold on to. Find one that came off a similar cid. engine/year and rebuild it. Simple is good, but free and simple is better. Ford used the same style carbs for many years. I had a '72 LTD that was giving me carb issues(throttle bushings leaked). Bought a used 400 that came out of a '74 f-250 and the carbs where very similar. Do'nt just throw a new carb at it right away... that takes all the fun out of this game we choose to play. Remember, it's not just "grandpa's pick-up" that your spending time working on.
