71 blazer, electric fuel pump?

[bp71k5]

I've got what looks like some kind of electric fuel pump on the passenger side frame rail. It's looks really old and the hoses that go to it are disconnected. Does anyone know what this is? I can try taking a picture later tonight.

Might Be

It might be a fuel switch. Mine had a single tank but had that under it. It allowed someone to select a secondary tank; the wires were even up in the dash but there wasn't a switch up there? Who knows why.

I have my fuel pump mounted on the pass side frame rail right in front of rear spring hanger. I don't run the mechanical pump though.

That's right about the spot I'm looking at. I have a mechanical pump on the motor which is working, but wasn't sure what the heck this thing was. Thanks for the confirmation.

I installed mine there, its not factory, just the closest spot I could mount it to the tank.
