My brother has a 2002 Chevrolet Astro van. The fuel pump needs to be replaced. He wants me to help him. (Honestly I don't want to for several reasons, I rather not discuss at this time.) I looked around on the internet for a few minutes on a howto article for changing the fuel pump. I found one that was pretty detailed. With the article I found was a suggestion of cutting an access hole in the floor of the van above the fuel pump to replace it. I really don't feel like dropping the fuel tank. The van (and my brother) is a p.o.s. So I am thinking of cutting a hole method. Does any one know what the shape of the floor is like on an Astro van? Is it flat? I am open to other suggestions. I could park it in a field and set the van on fire.
