how to tell if bronco came with two tanks?

[taslayer]

I have a 1971 bronco, it has two tanks, however I'm not so sure that it came with two tanks. Is there anyway I can be determine whether it did or not?

If you order a Marti Report it will tell you. What makes you think that it didn't? Something not look right?

the reserve is plastic, it has a electric fuel pump, switch valve under seat, gauge switch on dash

Heck, try to find the ones with three tanks!

Some years were plastic. (maybe original)

Stock parts. (maybe original)

My stock 73 has or had a plastic aux tank from factory

Those are all stock parts. It came that way.

As 'bowsher and others said. All stock (except for the electric pump) and normal.

the reserve is plastic

Yep. All year EB's had plastic auxiliary tanks with steel skid plates held in place by straps. In '77 even the rear main tank was plastic and slightly larger capacity. Held in place by a steel skid plate.

it has a electric fuel pump

Not stock, but many have been switched over for one reason or another.
In fact, it was very common for the rough-n-ready off-road, and rancher types that bought many of these rigs originally to install an auxiliary pump right away, in case the stock mechanical pump ever failed. Or sometimes to overcome vapor lock, or just for more versatility.

switch valve under seat

Stock again. All year models of early Bronco used a brass mechanical switch there. Owners got pretty deft at switching the lever too, if they ever forgot to switch the gauges and ran out of fuel!
There were at least two variations, where a couple of model years delivered to certain areas (usually high altitude or very hot) that got return line systems where the valve had six ports, rather than the standard three.

gauge switch on dash

Stock again. The switch might have been changed, but if it's chrome, has a long-ish toggle, a chrome bezel with the functions marked, it's stock.
Earlier models might even have had a manual choke and yours could have a manual throttle control knob right there by the switch. Used to control engine speed during PTO equipment use.
