Recently did a Weber carb conversion on my 86 b2000. Went to start it and wasn’t getting any fuel. Has brand new fuel pump, fuel filter, and sending unit. Lines are not clogged they were clean already when I went to go clean them. Is there something I’m missing. Any help is much appreciated. Thank you

 

Welcome to the forum.
Can you post any pictures of your engine and the engine compartment so that we can see what you have done so far?

 

How long did the truck sit without running before/during this conversion? I ask because I live in Arizona, and the gasoline in my Weber evaporates if it sits a week or two. So with all your changes, you may just need to use aerosol starting fluid into the carb throat or air cleaner to get the engine running a few seconds (may need to try several times) to get the pump primed.

Similar may be needed if you ever run out of gas. The mechanical fuel pumps are designed to pump liquids, not air.
