it's on a 351W, not much else to go by... cant id the engine or the carb (no tags I can find) help!
It's leaking fuel and I'm not sure what I need to get to fix it!

Take off the air cleaner, and look at the carburetor from on top of it, openr all the flaps (if there are any). How many venturis (holes)do you see? It will either be two or four.
So now you know if you have a two barrell or a 4 barrell.

Lets work on make next.

Part numbers for all autolite/motorcraft carbs will have be stamped into the drivers side front foot.
That part number will id the particular carb.

What type of vehicle is it installed on?

Hope that helps,

Thanks bill it's a 2v... Installed on a '79 Ford F-100 the motor was swapped by PO so I don't think that will help. (I found out that ford trucks didn't come with 351W)
I'm going to be taking it off tonight. I'll update you on what I find thanks for the tips!

Motorcraft 2100/2150 so be looking for a number on the drivers side front foot.

That will lead you to the path.......
