Just purchased a 1994 F150 XL that didn't come with any manuals. I'm about to do my first gas fill-up and wonder about the dual tank system. Is there a switch to alternate between the two or is it automatic? Is one a main tank and the other auxiliary? Later models on this forum suggest the front tank is the main. Does this apply to my year? With the price of gas, you can appreciate my not wanting to screw it up. Thanks in advance.
yes there is a switch next to your headlight switch to change tanks and both tanks are the same size if im right but dont quote that

Thanks for the quick reply! So, is one tank primary and the other auxiliary or does it matter? Would you also happen to know the capacities of each? My truck is basically a farm truck and hardly ever leaves the property except for gas runs and to pick up farm supplies. Any preference on how to apportion the gas between front and rear? I'm not too keen on filling both tanks as it may be months (if this year) before they're both run dry. Then again, the way gas is going, using the truck for storage might not be a bad idea. <g>
If you want a larger back tank replace the current one with a tank from a Bronco it will make you relocate the spare tire but gives you a 38 gallon tank. If the donor is the same age bracket it will have the right sending unit and pump installed. To keep rust out you will need to use a gas line antifreeze most fuels today are blended with ethanol which will absorb water from the air.
