On a 1992 C1500 "Sport" 5.7 w/auto, what amperage is the fuel pump relay? I think mine may need replacing (have owned the truck since new). Some of the parts places are showing 15 amp and 30 amp units. Original unit is #14089936, located on firewall. Thanks.

That same relay was used for mutliple items on the truck. Things like daytime running lights, AC and fuel pump used same relay. I believe from what I remember based on wire gauge, it probably a 15 amp. I never had an issue ordering from parts store with the number, seemed to always be correct.

I've ordered an AC Delco relay through Summit, so it should have the correct amperage being it's a Delco unit. Thanks.
