Chevrolet Repair: fuel pump relay location, fuel pump relay, 2 quarts

Question
I am trying to find the fuel pump relay location on a 1990 chevy g10 van 6 cyl 4.3 engine.

Have looked around the fuse panel, no relay.

What is the oil capacity for the differential?

Thanks for your help

Answer
Hi Pablo,
The relay could be under the hood, on the firewall, or one of the fender covers.
The diff....fill till it runs out the fill hole...about 2 quarts, I believe, but the owners manual would tell you, in addition to the type of oil to use.
