What was the original engine in the truck? If it was a 6 cyl. the truck was plumbed with 5/16" fuel line. V8s were plumbed with 3/8" line. The sending unit is also different (5/16" vs. 3/8"). The 5/16" line has been known to choke a healthy big block. The sock in the tank could also be coated with varnish.
