97 C1500 4.3 fuel pump?
 

A buddy of mine has a 97 C1500 Silverado with 4.3. His fuel pump just died. Went to order a new one, and the parts place is asking for all these codes "On the module". Already got under the truck, has the newer style plastic sender. Truck doesn't have RPO code EVA, which was one of their questions. Codes asked are GAL, GAP, GAV, or GDJ, GFK. Any pointers would help alot! Thanks

Here is a great place to get parts. He can just order a fuel pump if everything else works.
The codes they want are supposedly on the module. I think they refer to the types of connectors used.
