schematic needed 1983 F250 2wd

I need the area around the 2 relays that seem to power the fuel pumps. They are mopunted to the engine side of the firewall next to the steering column.

I am going to replace these relays with some standard Bosch ones and standard Bosch relay connectors so I want to understand what is going on there.


Thanks,

Dan

The problem is that these schematics are for fuel injected engines. The 7.5L for this truck is carborated. It isn't even feedback carborated.

Thanks though, I didn't realize that Autozone had thoes.

Anyone else?

They must be aftermarket pumps.

No, it's all stock and is the standard for 7.5L engines of that era that are carborated.
