My
Bronco came with the 33 gallon gas tank. The only other option
for 78 and 79 Bronco's was the 25 gallon tank. If you are lucky
enough to have the 33 gallon tank, then you also have the factory
skid plate. The 25 gallon tank did not come with a skid plate,
it uses two straps to support it.
I
decided to replace my old metal tank with a polyurethane tank.
There was some corrosion on the bottom of my old tank, and it
was just a matter of time before it would have started leaking.
This is a very easy swap to do, and well worth the $110 cost.
There is no more corrosion to worry about and the polyurethane
is much more durable than metal.
There
are a few things to note before you make the swap. The tanks
are available for 78's and 79's in both sizes. The 33 gallon
tanks are the same except for two things. 79 tanks have an emissions
hole on the top which connects to a line that runs up to the
engine compartment and connects to the charcoal canister. 78
model tanks do not have this hole. So if emissions laws in your
area require this, make sure you get the right one. If you get
the tank with no hole, you will need a vented gas cap to relieve
pressure in the tank. The other issue is the vent hose port.
If you have a 78 the vent port is left of the filler hole, and
just the opposite on the 79 models. Not a major issue but would
require some modification to make it work if interchanged.
